I have 3 PC's networked into a GVC router with print server. PC1 is a Win 98SE machine. PC2 is a Win 2000 Pro machine. PC3 is a Win XP Pro that is from work. I can access PC's 1 and 2 from PC3, but cannot access PC3 from either PC1 or 2. I can "see" PC3 from both PC1 and 2 using "find" or "search" for Computers. When I try to access PC3, a dialog box pops up asking for a password. The box has a message that a password is required to access resource "\\PC3\IPC$". I have tried to enter every password that I have, to no avail. I have looked through all the settings I can think of, to no avail. PC3 is from my work and has only a few user profiles, mostly for the administrators. I use a program called Netswitcher to change the network settings from work to home, and use Cisco VPN client to access my work e-mail from home. Any help would be a lifesaver. Thank you.
