I am running into major issues with kixtart and Windows 2012 server.
I use it to map drives by calling the following batch file located in netlogon:

@ECHO OFF
REM %0\..\Kix32.exe /f %0\..\bis.kix

The problem is that the script works only if I add the word explorer at end of script or if I manually run it:
Like below:

@ECHO OFF
REM %0\..\Kix32.exe /f %0\..\bis.kix
explorer

It works fine in other versions of Windows but not in 2012.
I confirmed that is not a GPO issue because if I add calc.exe at end of script it launches calc but it does not map the drives.
