Vista - Windows Vista HP to Win 2K Pro troubles

Have 4 computers wired into LAN. 1 XP Pro, 1 Vista Home Premium, 2 Windows
2K. All can ping and see one another. All have identical usernames &
passwords. Logged in as identical users. Firewalls are disabled. All
access internet perfectly.

Can access XP file shares from 2K & Vista. Can access Vista and XP from Win
2K machines. Only problem remaining is Vista to 2K machines.

Get uname and password prompt when accessing 2K from Vista. Put in correct
password. The box adds the name of the Vista machine in front of the
password (compname\uname) and sends "incorrect logon" error.

I apologize if this has been posted before. I've read all the postings for
the last 6 weeks and need the Vista machine for my business.

Appreciate some help.

Can't tell why it has this issue, but add the same username which logon Vista on 2k computer should work.
