network printer failed to print unless authenticated

Hi,

Two machines. Server running Vista home basic and client running Vista
business, both on the same private network and workgroup, both have
network discovery printer sharing file sharing on. I installed a
printer on the server which prints fine locally. The problem is, it
looks like everything I do from the client need to be authenticated,
meaning:

1. when i search for a network printer from the client I can't find
it, unless I browse to the server, which required entering a user name
password of a server user account

2. when i try to browse to the server from "Network" in explorer, I
always have to enter a user name, password

3. when I print from the client using the network printer, it fails.
However, if I do 2., which is to connect to the server at least once
entering the user name password, i can print.

It looks like unless I get authenticated on the server I can't print.
So now every time now i try to use the network printer i have to at
least once click the server in "network", enter user name password,
then I can print. Is this normal? Thanks.

Nick
