kix32.exe and kixtart.kix are in Netlogon so that should be fine...
Now what do I have to fill in in the client
Do we mean the same thing by the way ?
I use the logonscript box of a useraccount in the AD of our server...is that correct?
just kix32 or kix32.exe or kix32.exe kixtart.kix
And what do you mean by "button profile"?
