Suddenly cannot connect to an XP machine (others work)
I have a small home network setup with a handful of Windows XP machines. I recently upgraded one machine to Windows 7 and everything was configured and working. This morning the Windows 7 machine will not connect to one of the XP machines. I set up the Windows 7 machine with two logins (my wife and I) and I have the same accounts and passwords stored on the XP machine. This was working fine. The XP machines are setup in a group and the Windows 7 machine has a homegroup by the same name (not that this matters as I think this is a Windows 7 only thing). I have the userids and passwords stored in credential manager. I entered them as group\username and then password. I can ping back and forth between the machines so I know they see each other.
No matter what I do I cannot get this 7 machine to connect to the XP machine. It could have been any number of software updates or something that could have caused this problem. Recent changes that I can think of are adding Windows Antivirus. Does anyone have any suggestions for diagnosing this issue? Thanks.
