Logon Script in VBScript

[Guest_imported]

I wrote a little Logon Script in VBScript. The Script runs fine when called on the command line (Cscript SCRIPTNAME) no matter if it is called on a Win98 or NT machine.
I used a Logon.bat (used if %OS%==Windows_NT ....) to call the script via cscript at logon. The Script runs fine on NT but i get an error on the Win98 Computer.
The Error points to this line: "strUsername = WshNetwork.UserName"
Why is this working from command line and not while login? I searched the MS Knowlegebase and found that on 95 and 98 i have to use something like this:
While strUsername = ""
strUsername = WshNetwork.UserName
WEnd

I did it, but the error still points to the line where i want to get the Username. I tried the following:
"WScript.Echo "ComputerName = " & WshNetwork.ComputerName"
getting this line on the Screnn: "ComputerName = "
Is the WshNetwork Object not working on login? Is there another way to get the Username? I need it for a logon script for 95/98/NT.

Thanks

Give the system sufficient time to retrieve the UserName :

While strUsername = ""
strUsername = WshNetwork.UserName
WScript.Sleep 200
WEnd

In many different instances, this is necessary to ensure the proper working of a script.

ps. If you have worry to get caught in a infinite loop, add some time limit control to breakout gracefully. But this is usually not necessary.

Thanks for the help. I tried it, but i still get the same error. Even if I give the system more than enough time ( sleep 2000 before and after the statement should be enough).
I wrote down the exact error. here it is: script.vbs(11,5) 0x800704DD
the strUsername= is in line 11.
Maybe someone can tell me what to do? Or is it impossible on a 9x system to retrieve the Username/domain/computername while in Logon Process?
I tried a workaround and the script now puts itself into the Registry RunOnce section, that is executet after the logon scripts. Then it works fine and without any Error.

A Second thing: Is there a function to get the groupnames the user belongs to? On NT i know it works with some tools. Any idea for 9x? Would be great if it works with WSH.

Thanks

Hello MartinB123.

It does seem to be a limitation on Win9x, having to wait until a logon has run its due beforehand. Standard workarounds are either
[1] that to put the script to work with the command :
WScript.exe <script file>
in a value under the key HKLM\Software\Microsoft\Windows\CurrentVersion\Run (as you probably know);
or
[2] that to drop a shortcut of it to the Startup folder.

As to the verifying of groupname a user's account belongs to, you would have to take a look into the ADSI support :

http://www.microsoft.com/windows2000/techinfo/howitworks/activedirectory/adsilinks.asp

and its free resources download :

http://www.microsoft.com/ntserver/nts/downloads/other/ADSI25/default.asp

ADSI Group methods support IsMember to check whether a user is a member under a groupname.

Cannot provide more help than this. Maybe somebody may intervene if you would like to raise precise problems.
