Looks good. If the window did not stay open after the script finished beside for the 10 extra seconds that the Sleep 10 does then the batch file is the culprit.
You could run the script from a batch file like shown below. If you have nothing else then Win2K, Win2K3 or WinXP or up then there is really no need for all the stuff that is in the batch file you posted. Only thing you need to do is change YOURDOMAINNAME to the actual domain name and change the name of the script to the actual name of the script. Also you should be sure that kix32 and/or wkix32 and the script are in the proper folder. If not move them or alter the path in the batch file below.

 Code:
\\YOURDOMAINNAME\SYSVOL\YOURDOMAINNAME\Scripts\kix32.exe \\YOURDOMAINNAME\SYSVOL\YOURDOMAINNAME\Scripts\yourscript.kix
