Hi,

Here are a few tricks found in various newsgroups which did it for me.
Please note that the tips below will only using an admin account, not with a
standard account.

On the XP machine:
- enable the Guest account on the XP machine
(don't know why this has to be done, normally this account is disabled)
- check the permissions on the XP share$ folder (Everyone read)
- check print permissions on the security tab
(allowed print for 'Everyone' and 'Network' on XP machine)

Vista machine:
- the account on the vista machine must have a non-blank password to log in
- allow Vista to discover the network
- allow Vista to do file sharing
- created a Local Port on Vista, (Local Port like \\XPComputer\YourPrinter )
and
connect to it
- as an alternative, try to connect to the YourPrinter via network
(find \\XPComputer and its shared printer)

This works fine for the admin account, but not for the Standard Account on
vista. I hope someone will come up with an answer for that as well...

Cheers, Daniel
