Network logon failure unknown user name or bad password

I am trying to network two win 7 computers. I get the screen Logon failure: unknown user name or bad password.
I have gone done the following: 1. Same user names and password 2. disabled windows firewall and avg free. 3. Answered "On" to all private network selections. 4. Local security policy to classic 5. Shared files I want to access. 6. Home group named as workgroup

The computer comes up in the Networking and Sharing. When selected I get the screen Logon failure: unknown username or bad password. I have even had my ISP pro look at this and he cannot figure it out. Same thing has happened to me in vista. I am using new win 7 installs. I can map drives with ip addresses and access.

Please advise if anyone has a solution or suggestion.

Thanks, James

I had the same problem. I know with my laptop i don't seem to have a problem with it, but now with my desktop it's a hole different story. It keeps trying to use a domain on my desktop to login. I know i'm running a windows home server. I have tryed changing the domain to match my windows home server. But it's still not working.

I took your advise and sync all the clocks. That did not help. Well I have done all the standard things, same user name, same password, firewall check, netplwiz adjustments, shares, ip pro came over could not figure out. Now I have 3 xp, 3 vista, 3 win computers on home network. I have one Laptop 64 bit vista ultimate that can communicate with most others. I guess I will let some time pass until I figure out this problem. My internet works fine and I can see all other computers fine from win 7
