Set up 25 new Xp pro machines with local and domain
username and password the same. Shared printers and
everything was fine. Another admin changed local username
to "admin" and changed the passwords. Now, even logging
into domain, can't brower any other machines to get to
sharded printers? Get message "//name is not accesible.

The network path was not found'
Any ideas?
