Hello Tim and welcome to the board.

It could be a lot of things. It could be that someone was messing with policies.

Please answer a few questions first.

1. What version of KiXtart are you using?
2. What client OS do you support? 9x/nt/2000?
3. When did the problem start?
4. Did anyone admit changing anything?
5. Please post your BATCH file that launches KiXtart
6. Please post the complete KiX script

When posting please use the Instant UBB buttons to enclose your batch and then your script within the [ code ] tags.... this will keep the formatting of your script for us to look at and give you further advice.
