I have 4 compjters in an office. 3 have windows XP, one has windows 7. The three XP ARE IN THE SAME WOORGROUP, THE 7 is in a different workgroup. All 3 XPs can see each other. The 7 has to sign into the XP workgroup to use the shared printer. But all of a sudden I cannot log onto the XP worgroup. The XP machine that has the shared printerjusts boots up under Administrator with no password. So when I double click on that XP printer from my Win 7 computer, I just use "Administrator" as user id and blank for password. But it keeps coming back as if the userid or password is incorrect. Any ideas?
