Can't Lock Server

[Mike]

When I hot CTRL + ALT + DEL on both my PDC, and PDC
the "Lock Computer" option is grayed out. I think I have
a DNS and WINS problem, Could this be causing this to
occur?

Possibly a Group Policy setting at some level - domain or domain controller would be
good places to check. Look under user configuration/administrative
templates/system/logon&logoff where the option should be. You could try setting it to
disabled for domain controller GPO to see if it helps. --- Steve
