OK guys... Got the real fix for this!

The problem was that, for some reason, the logon scripts or startup scripts was exiting too fast for the kix script to run.

I was able to put the following into a .bat file and it ran beautifully!

\\servername\share\wkix32.exe \\servername\share\dns.kix
PING -n 3 127.0.0.1>nul

The number 3 represents about how many seconds you want the script to pause for.

I copied the .bat file to the same share, and put the following into the startup script

\\servername\share\dns.bat

Thanks to all for your help!
