Printer Sharing

[Vazo Mokatz]

We recently had to Windows XP pro machines that were not
members of our domain however tey were sharing resources
from one another. On of the computers (computer A) was
using a printer from computer B and all was fine. When
we joined the 2 computers to our domain, computer A still
required to use the printer on computer B. When we
issued the command "net use lpt1 \\parts1\hp1100" it
would come up and ask for a user name and password.
While logged on as the user, every account we tried to
enter would come up and say access was denied. If I
logged on to computer A as the domain administrator and
issued the same command, it wouldn't prompt me for a user
name and password and would map LPT1 correctly to the
printer share on computer B.

Is there anything I can do to resolve this?

Thanks in advance
