Solution: Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.

In Windows 2003 SP1, this may be annoying sometimes if you don’t know what’s really happening. 

Problem: I have started building a Windows 2003 server (SP1) in the lab. I already have downloaded few Microsoft Exchange Patch files from Internet on our file share. I copied one of those Exchange 2003 patch setup file to my new server and try to run. Boom…I got an popup saying,


Solution: It turn out to be Microsoft is blocking files copied from other computers. That’s not the popup saying to us :-0 !!!!. Open the properties of the copied file (right click –> Properties). I found this,


The picture speaks itself. I don’t have to explain it.

Deleted a Recurring Meeting without sending updates??? Solution is here.

Another day in the office. A cry came through phone from an admin who manages multiple conference rooms. "Please Help!! I have deleted a recurring meeting without sending updates? IT..Please help us to delete the meeting from all attendees".  Mind it it’s more than 20 attendees and she don’t want to call everyone to tell them to delete manually. It’s embarrassing for her.

I assured, "I am all here to help her issue".

Okay that must be a easiest job. 10 second work for a Exchange administrator like me. I open the conference room mailbox and opened the "Deleted Items" folder.  Within 10 seconds I realized it’s not a easy job. Because I didn’t find any deleted meetings in "Deleted Items" folder. What else? I tried "Tools –> Recover Deleted Items". No luck over there too.

Little investigation, I finally found out how to recover the deleted item and save the day. Here is how.

1. Open the Conference Room mailbox in Outlook.
2. Open Calendar (by clicking Calendar Button in Outlook 2003 and up OR Calendar Folder in Outlook 2002 and down)
3. Click Tools –> Recover Deleted Items
4. Find your deleted meeting and recover it.

I recovered the meeting and I called her. I told her to delete the meeting again, but send updates this time. So like I said, another day one of those Exchange admin guy saves the day. 🙂

Find the Display Name from email address from Active Directory

As a Exchange Administrator, I supposed know the answer for the following question in a blink of an eye. 

Where are the mails go when I send to this email address?

Well, that’s what I thought. It’s a more general email address like I searched for Distribution list or a mailbox or even a contact object. None. Best thing about "Active Directory Users and Computers" is you can NOT search by a email address.

My instinct says it must be a "Mail Enabled" Public Folder. So I searched through the public folders hierarchy.  There is lots of them and none of them has the specified email address attached. Exchange System Manager blankly said it delivered locally to the server.

I decided to use my special skill called "Scripting". I wrote the following script to get the display name of the email address from the Active Directory. Voila!!! I found what I was looking for in seconds.

Below is that script. If you want to use it, change the "Domain Name" for DomainContainer variable.

‘*********                       GetDisplayName.vbs                 **********
‘********* Parameters: email address                                **********

DomainContainer = rootDSE.Get("defaultNamingContext")

Set conn = CreateObject("ADODB.Connection")

sMail =  "SMTP:" & WScript.Arguments(0)

      WScript.Echo FoundObject.CN

Playing PLS (WinAMP) file in Windows Media Player


Do you ever wanted to play PLS (web broadcast) files in Windows Media Player? I do for good reasons like below.

1. WMP can buffer up to 60 seconds (or 1 Minute) of the broadcast. Somehow I can’t find it in WinAMP (at least in free edition)
2. My Keyboard support WMP for play, pause, etc.,, but NOT WinAMP

I tried opening the PLS file in WMP, it doesn’t know how to parse the PLS file. But, if you open the PLS file, copy and Paste the HTTP URL into WMP, it plays.


For Example, the typical PLS file looks like this,

Title1=(#1 – 10/50) MoonBeat Radio

If you copy the HTTP URL (, Open the WMP, Click Ctrl–>U for Open URL and paste the URL, WMP buffers and plays nicely.

Now, I know the above info..who are they kidding? I wrote a VBScript and made WMP to play the PLS file automatically. For example, I go to a Radio web site, click on PLS file link (usually says "PLAY" Button or URL), my script open the PLS, parse and open WMP with the provided HTTP URL. So I don’t have to install an extra player to listen Internet Radio on my work laptop.

If you like the above idea, use my following VBScript and CMD file.

1. Copy and Paste the following script into Notepad and save it as "PlayPLS.VBS". NOTE: While saving the script from Notepad, You NEED to type the vbscriptname.vbs in QUTOES. e.g., "PlayPLS.vbs". Otherwise it will save as PlayPLS.vbs.txt

‘*********                       PlayPLS.vbs                        **********
‘********* Parameters: PLS file name                                **********
‘*********                                                          **********

Set WshShell = WScript.CreateObject("WScript.Shell")
Set oArg = WScript.Arguments
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Dim fso, f
Set fso = CreateObject("Scripting.FileSystemObject")

If oArg.Count = 0 Then
    WshShell.Popup "Invalid Arguments…Please provide the PLS file name.", _
7, "Play PLS in WMP",0
End If

sPLSFileName = oArg(0)
Set f = fso.OpenTextFile(sPLSFileName, ForReading)

Do While NOT f.AtEndOfStream
    sText =  f.ReadLine
    If InStr(UCase(sText),"FILE") > 0 Then
        sURLText =  Split(sText,"=")
        sURL = """" & sURLText(1) & """"
        sCmd = "WMPlayer " & sURL
        WshShell.Run sCmd
        Exit Do
    End If

Set fso = Nothing
Set oArg = Nothing
Set WshShell = Nothing

2. Copy and Paste the following text into Notepad and save it as PlayPLS.cmd. NOTE: Use the "double quotes" when saving the name in Notepad.

C:PathOfTheFolderPlayPLS.vbs %1

3. Open your favorite radio station (mine is, right click on PLS file link (or PLAY button) and save it on your desktop.

4. Open the file properties of PLS file (by right clicking on the PLS on the desktop and select properties), Click "Change" button next to the "Opens With:" text. Select the PlayPLS.cmd file by browsing to the corresponding folder and select the cmd file.

5. You are done. Go to your favorite radio web site again and click on "Play" Link. See it open in Windows Media Player.

6. Don’t forget to Thank me.

Mysterious Mails, Delivery Notices, Bounced mails Vs Outlook Delegates

This is what happened to me on one fine day. An Executive Admin complaints that she was getting Exchange mail delivery notices and bounced mails (NDRs) from an unknown user. 

She said it’s pretty annoying that she sends mails to bunch of users and gets bounced mails from some unknown (or long gone) users. I assured her that I will find out the issue and solution.

I laid back with my tea and thinking about the issue. If she sends mails to someone, but she gets NDRs (delivery notices in other cases) from a user who was not in TO or CC or BCC list. I know that Outlook Delegates are gets mails and meeting requests behalf of whoever delegated. I finished my last sip of tea and said myself, That is it.  "Delegates".

I started wondering about how to find out if anyone is delegated to someone else or not. After a few Live and Google search, I found out Active Directory stores the delegates and delegated users list in User properties. The following properties has the list of delegates,


I wrote a script to find out who’s delegated to whom. I ran my script against the "bunch of users" given by Admin. Voila!!! I found the list of delegates, made some phone calls and fixed the issue.  I informed the admin with the details and she praised "IT is great!!!" as always.

If you are the guy who is sipping your coffee or tea like me thinking about the same issue, Help is on the way here in this blog.

1. Manual Lookup of delegates

1. Open the ADSIEdit.msc by typing it in Start –> Run.
2. Expand Domain [domain name] container and find the user you want to check
3. Right click on the User and select "Properties"
4. Find publicDelegates and publicDelegatesBL properties and check the value

2. Use my Script to find out the delegates

Copy and Paste the following script in Notepad and save as "Delegates.vbs" to an known location.
Open Command prompt, go the directory where you saved the Delegates.vbs file.
Run "CScript Delegates.vbs <UserAccountName>"

e.g., CScript Delegates.vbs JDoe
CScript Delegates.vbs BGates

If you find what you looking for, Thank me.

‘********* Parameters: Active Directory User Account Name           **********

RunAs using VBScript

If you want a VBScript to run a program using RunAs DOS command, go straight to the bottom of the blog. If you want to read the build-up for the final product, keep reading.

Time to time I came across I wanted to run a script or program as administrative privileges. The few needs are like,

  • Install a program or do something on client machines via logon script
  • Run a program using different account

Duh! RunAs command. Sure RunAs command works, but using VBScript??? You can find a VBScript example for running a program using RunAs command like below,

set oShell= Wscript.CreateObject("WScript.Shell")

oShell.Run "runas /user:domainaccount ""Notepad.exe""", 2      ‘Note 2 means minimized Window
WScript.Sleep 100

oShell.Sendkeys "password~"    ‘Note the ~ character in the end. ~ means ENTER


What’s wrong with the above script? After all it should work as expected. You know who the villain for above script. Guess…..OK. It’s attention hungry programs. When you run this script, it might send the password keys to wrong window,  while you running along with zillion programs in foreground and background. So what to do?

I rewrite the script few times and tested the script running along many programs. (Take ‘many programs’ as WinDVD, IE, Downloading a file in IE, Notepad, Command prompt and Active Directory Users and Computers). The final product is below,

Dim oShell
set oShell= Wscript.CreateObject("WScript.Shell")

oShell.Run "runas /user:domainuser ""program.exe""",2     ‘Note 2 means minimized Window
WScript.Sleep 100

For i = 0 to 10
      oShell.Popup "Opening Program.exe…",3,"Administrator",0+64  
‘3 means 3 seconds, 0+64 means OK button with Information Icon

      Activated = oShell.AppActivate ("runas")
      WScript.Sleep 10

      If Activated = 0 Then
             oShell.Sendkeys "password~"           ‘Note the ~ in the End..~ means ENTER
             Exit For
      End If


Few Tips and Tricks:

  1. If you want to run a VBScript in runas, try running RunAs /user:domainuser "WScript script1.vbs"
    • RunAs command run only executable files, so *.VBS or *.JS will not run
  2. If you want to run an *.MSC file, try running RunAs /user:domainuser "MMC test.msc"
  3. If you want tor run an Non-Executable file (other than above), try creating a DOS batch file and run the batch file using RunAs
  4. It’s not really safe to leave the VBScript file command location. Passwords are visible to any eyes. Try Encoding the VBScript using VBScript Encoder (can be downloaded from Microsoft).


For non-believer of my above VBScript sample, here is the nice list of alternatives.

Display more than 2000 Users (objects) in Active Directory Users and Computers Console

I have had it. We have more then 2000 objects to be displayed in Active Directory Users and Computers console every time I open it. This goddamn console doesn’t stick the Maximum number of items displayed per folder. Somehow it goes back to 2000.

Then I found a workaround by creating my own MMC console. That resolved my problem. Now, I am very 🙂 to see all the users in ADUC console every time I open it. No nagging warning popup windows.

If somebody frustrated with ADUC console with the same problem, here is the help to make a custom MMC console with custom settings.

1. MMC” in Start -> Run.


2.  Select File  -> Add/Remove Snap-in. Click Add.


3. Select "Active Directory Users and Computers”. Add and Click OK.


4. Select the Active Directory Users and Computers in MMC console. Click View and Filter Options. Type the number (of objects you want to see). Click OK to Close.


5. Click File -> Save. Type the name and your own location. It will be saved as *.mmc e.g., Active Directory Console.msc.


6.You can double click that saved mmc file (e.g., Active Directory Console.msc) to open the ADUC console with your own custom options. Custom options will stick permanently.

7. Thank me if you find it useful. 😉

VBScript: Monitor a folder for new files

The Following link from MS Technet Script Center was exactly what I wanted.

Link to Hey, Scripting Guy! How Can I Automatically Run a Script Any Time a File is Added to a Folder?

Scripting guys at Technet are doing a great job on scripts and examples. I usually I look in script center before I try searching all over the Internet. I met Peter Costantini and Dean Tsaltas on a NT user group occation. Awesome guys.

Exchange ActiveSync Gripes

Notes and ActiveSync – Why?

I came pretty disappointed when I realized Exchange ActiveSync is not supported with (Outlook) Notes sync. So,I looked Exchange 2007 Active Sync and no where mentioned Notes sync is on the horizon. So, I take it Notes sync will never be included in ActiveSync now or in future.

According to this link, Exchange 2007 ActiveSync can sync voice messages and fax attachments from mailbox, but NOT "Notes".

I don’t know what complication MS has with Notes synching using Exchange ActiveSync. Otherguys on the same block (BlackBerry, Good, iAnywhere,Seven, etc.,) have no problem synching Notes.

PocketPC/Smartphone Backup and ActiveSync – Missing feature

You know what else would be really cool feature…over the air Backup and Restore. I know iAnywhere has it with OneBridge software. It’s a full backup (including memory card) to the server wirelessly. If it saves you at least one time  in a critical situation, it’s worth it. May be, some third party guys should work on extending Exchange ActiveSync if it is possible. (On this paragraph,I have to mention that WM5 has no in-built backup feature and I don’t see it in ActiveSync 4.5 Beta 2)

ISA 2004: OWA, RPC/HTTP, OMA, ActiveSync on same Listener (works)

Here is one conflicting information goes around the Internet. ISA 2004 cannot publish all four Exchange features (OWA, OMA, ActiveSync and RPC/HTTP) in one single listener. I have searched the Microsoft site (technet) and  Here is the links for related ISA 2004 and Exchange publishing.


None of the above links describes how to run all 4 features published in one single listener on same External network card. The problem I am talking about is this….

-OWA needs to be setup with Forms Based Athentication on ISA 2004 server (more secure design)

– Rest of the items (OMA, ActiveSync and RPC/HTTP) requires Basic Authentication (over SSL). Outlook 2003 or mobile devices will not handle the Form Based Authentication, so it needs to be on Basic authentication.

So, all the Microsoft and other documents leads to create two different listeners (one with FBA and one with Basic authentication). Two listener cannot listen on same IP address and same port (443). Two different listener means two different IP addresses.  And it also means two different domain names ( and It complicates more like we have to buy two different digital certifications from provides (VeriSign) unless you choose to run Certificate Services in home.

Then, I found this article and may shed light for the solution:

After I reading the above link, I realized this is not going to work for me. We bought a SSL certificate from legitimate provider and we don’t run certificate services at my company and we don’t plan to setup. For some small business and other companies, it may do some magic.

I was frustrated and about to gave up. I fiddled around and found something in the middle. All four features (OWA, OMA,ActiveSync and RPC/HTTP) are working on a single listener. Here is my setup. See the drawing and I will explain it below.


















Here is the steps:

– Create a Listener called FBA_443_Listener with above settings in the drawing. Note this listener has only FBA selected. Don’t forget to set the default domain (your AD domain). If the users are from different domain in the forest, they have to type "domainusername" format.

– Create a Firewall Rule with Mail Server Publishing Wizard. Name it "OWA Publishing Rule". Select only OWA during the wizard. Setup the rule with above settings as it is in the drawing. When asked, select FBA_443_Listener. You need to enter path after finish creating the rule.

– Create a second firewall rule with Web Server Publishing Wizard and name it "RPC/HTTP,OMA and ActiveSync Publishing Rule". (Note the bold letters, this has to be created using web server publishing wizard and NOT using mail server publishing wizard). When asked, provide the path name as /rpc/* with your OWA domain name ( Make sure the settings are correct with above drawing. You need to add all the paths manually after creating the rule.

Voila! It worked. I am no geek on ISA server side, but here the explanation. The magic here is you create the rule for RPC, OMA and ActiveSync using WEB SERVER PUBLISHING WIZARD. I still don’t get it that how Outlook and my Mobile handles Form based authentication with above setup. But some how it handles it.

One possibility is Microsoft made Outlook and WM5 to manage the FBA through the latest patches. OR ISA 2004 with SP2 handles the NON Browser calls with Basic Authentication. So, don’t forget to patch your servers and clients.

Here is the result:

– Outlook Web Access link is provided with FBA logon page

– OMA provided with Basic Authentication page

– ActiveSync works and NO errors

– RPC/HTTP is provided with logon window in Outlook 2003 and it works without errors

This above setup works and I can do all four Exchange features beautifully.  With all that above, I am running ISA 2004 in single network configuration. The listener is set to listen on local network.

Hope it helps someone desperately looking for the information.
