%SERVERLOGON% can not work, because the name of the variable is %LOGONSERVER%.

Now I changed my script and I call it this way:

\\%USERDOMAIN%\NETLOGON\wkix32.exe \\%USERDOMAIN%\NETLOGON\logon.kix

It works fine, but I read, that if wkix is used, it should be started this way:

start /w /b \\%USERDOMAIN%\NETLOGON\wkix32.exe \\%USERDOMAIN%\NETLOGON\logon.kix

What do you think about that and what should be used? wkix32 or kix32?
