Kent, I tried your suggestions to no avail. Jens, as I said, I don't know the source of "ingroup32" or "ingrp" but have found that "ingrp32" works also. I ran kixstrip against the script and it found no errors. My logon process still uses an older version of kixtart that included "unlock," "ingrp32," "setw," and "unstick." I copied the 4.21 files to my net logon directory to demo it and came across this situation.

Nonetheless I have remedied my problem. Operator malfunction. Interestingly enough, the three unknown group functions either just did not work and mapped the drive anyhow or they ignored the group requirement and acted on the userid requirement.

Thanks for your time.
Scott
