Windows 2000 SP4 workstation running Novell Client 4.91 SP2 logging into
Netware server 5.1 SP8.

Sometimes after a fresh reboot of the workstation, when I try to login, I
get "LOGIN-LGNWNT32.DLL-890: The specified server is unknown.". I press
the OK button on the error message and the login script fails on all of
the drive mappings for the offending server, but works fine for all other
servers.

I do a SLPINFO /ALL but all is well:

The offending server is the DA, by the way.

If I let the workstation sit long enough, I can eventually login to the
offending server.

Anybody know what's going on here????
