File sharing with Windows 7

I have a Windows 2000 file server, home use, and all of my XP machines read it with out any problems. So did Windows 7..........for one night!! I set the HomeGroup connection settings to "Use user accounts and passwords to connect to other computers." Everything worked fine last night, I shut the computer off and went to bed. This morning its telling me there is an error with my user name and password. No settings were changed that I know of. Does anyone have a clue what happened?

You try re-booting the server?

Ken

Yes, and I even reinstalled Windows 7 on the client thinking it could have been a bad update from this morning.

Clean re-install? did something change in networking? homegroup vs workgroup or domain?

Ya, clean install. Reformat and everything. No changes to the network settings. Workgroups are the same on both machines.

why not check event log to see what errors are being generated

I just tried to read the Windows 7 machine from the Win 2000 and saw everthing just fine. Could it be a firewall setting?

Not much of a user of the event log. Can you tell me where to find it?

Sure what firewall?

The one on the Win 7 machine

windows firewall. try turning it off and see if the prob vanishes. your behind a nat router, right? like cable>>router>>server>>pc, etc
