We are trying to connect a new PC to a NW6.5 network using the latest
client. Drives mapped in the login script don't get mapped, and trying
to map a drive manually results in a "Can't find server .." type of
message, even though we have just navigated to it.

The irritating thing is, occasionally the drives do get mapped (eg
immediately after installing the client software and sometimes when
waking the machine up after it has gone to sleep).

Any ideas anyone?
