sealeopard, I have added the exit and will see if that shows a noticable different.

LLigetfa, I have discussed that with the SMS team, but they wanted to keep it separate incase they wanted to adjust it in some fashion. With it separate, there would not be any need to alter the Kix code.

Although I typed a bunch of crap in my original post, the real point of what I would like to discuss is the observed issue that the logon script window WAITED for the "%comspec% /c START SMSLS.BAT" to finish before the window closed.

In case anyone is interested, this is my batch file.
code:
@ECHO OFF
