To answer the questions raised so far:

1 - Permissions seem to be OK. They are the same on all servers.
2 - At the location with the problem, the Kixtart script will not run. Windows 9x users call the script from a batch file. The batch file portion runs fine, but the script does not rub. W2K users call the script directly, and no script runs.
3 - Scripts are called from the user account (not a group policy)
4 - All DCs are in a single domain.

A couple of other bits of info:

If I log on as the same user at any other site, everything is OK. The problem appears to be Server specific.

Thanks for the replies so far.
