printer access denied after reboot

I have a printer shared on another computer. Allof the computers on the
network print to this one by default. I setup a new computer though, and I'm
having a problem. After you reboot and you try to print, it says you must
first install a printer. If you go into the printers the shared printer
shows access denied. I can delete it and "reinstall" it again and it works.
It always changes back after reboot though.

btw, when I install the printer I navigate to the shared computer on the
network and "login" using one of the computer logins, either gary and no pw
or main - password. Either way it does the same thing after rebooting and
gives the access denied message.

The hosting computer is XP Pro and the one with the problem is Home.

Please help.
