What is the problem???

MVP Hans-Georg Michna has a small network troubleshooter that can often pinpoint the problem. He wrote it for XP but it may help you. - Small Network Troubleshooter by Hans-Georg Michna  - Hans-Georg Michna on Vista-XP Networking (may be useful for Win7 also)

Generally speaking if you are getting requests for usernames/passwords the cause is that you do not have matching user accounts/passwords on all the machines. You think you do but someone renamed the generic "Owner" or "HP_Administrator" account with their own name, not realizing that this doesn't change the actual account. In this case you might think you have an account "Bill" on all three computers but one of those accounts is really "Owner". You solve this particular situation by creating "Owner" on the other two computers where it is missing. Check by looking at the actual user profile names in C:\Documents and Settings in XP, C:\Users in Vista/Win7. Or you have "Bill" correctly on all three machines but the password is different on one of them, perhaps even because of a typo. So double-checking is in order.
