First user logon … remains.

Network: Netware 4 with NT and Legacy svrs. Logon thru Netware client 4.8, then NT4. So far, occurs only on laptops (Dell CPX and CPI).
Issue: Name and context of first user to logon (me – IT support), remains even after several other users have logged on. Causes no other problems except user curiosity … and I sometimes get locked out.
Question: How do I get rid of this? Heard of a registry hack or a Novell setting.
