Question : %clientname% environment variable not present at login script on windows server 2008 TS

Hi there,

I have a strange problem here on my new Windows server 2008 Standard with terminal services.
I have a script to add printers in association with the clientname (it works correctly on my 2k3 TS for over 2 years now)

But on my new 2k8 server, I can't get the %clientname% variable at logon.

I've made some testing by using a batch file with the command "Set" in User Login script by GPO and then running the same command in the user Session :

here are the results :

as you can see, the %clientname% returns my computer name (RNDEP) only when it is executed in the user session but not on the User login script by gpo.

If I run manually the vbs script to add printer into my session on the TS, the printers are mapped without problems.

Answer : %clientname% environment variable not present at login script on windows server 2008 TS

finally, I have contacted Microsoft. And here is the result :
"I am providing you a copy of our scope agreement for your issue: 2k8 system fail to resolve %clientname% in logon script on terminal server with loopback enabled in replace mode."

to resolve this issue, they asked me to change one setting in the GPO :
Run logon scripts synchronously
Setting Path: User Configuration/Administrative Templates/System/Scripts

It's not a KB article and it will not be one they said.
