XP SP3 is used. The Simple File Sharing is not enable.
Ping from W7 to XP goes through.
The same log-on user name and password are used for XP and W7.
XP machine is visible from W7.
Error message is "Unknown user name or bad password. The same message when attempting to access from another W7.
Initially it was working but after an hour or so, it quits. I rebooted the router, XP machine and W7 machine but the situation remains unchanged. There is no problem networking between the two W7s.
Any suggestion is appreciated.

It was working, but now it's not? What has changed on the XP or 7 computer? What security software are you using? What directories are you sharing?

Using the set up described in the link below seems to be the most reliable way to get sharing to work between Windows 7 and XP. Most any A/V software can all cause hell and havoc for sharing folders or files so there is always that possibility as well.

How to make Windows 7 work with older Windows versions for networking and file sharing.

There are many other ways to accomplish this, all I ever needed to do was to run the network set up wizard on the XP machine then set up sharing on a per folder basis then use the advanced sharing settings on the Windows 7 machine.

There is not any change I am aware of. The security software I am using is MS Security Essentials. It was working from both of the two W7s. I felt puzzled.
Edit: I added another W7 to the network and tried but it does not work. If anything happened since, it appears to be at XP.

The reference appears to be how to let older machines access W7. Note that there is no problem networking among W7s, and the problem is accessing older machine from W7. It appears to me that something with XP needs be changed. Is this valid logic? By the way there is no problem accessing W95 and W98SE from W7 on the same network.
