I have a wired network of 3 computers - XP, Win 7 and Win 8. The network works fine between all the computers, file sharing and remote desktop, but after a few hours the XP computer loses access to the Win 7 computer.
From my XP PC, I get an error message of access denied when clicking on a mapped HD on the Win 7 computer, yet when this happens I can still use remote desktop on the XP computer to connect to the Win 7 computer. I can also access any HD on the Win 8 computer from the XP.
If I go to Network Places, when I click on Workgroup I get this access denied message using the XP PC.
“Workgroup is not accessible. you might not have permission to use this network resource. Contact administrator of this server to find out if you have access permissions”
When this happens if I reboot the Win7 PC, then the XP PC regains access again to the Win 7 PC.
About 3 months ago I would never lose access on the XP computer to the Win 7. I reverted to an image file for the Win 7 computer to return to the way it was 5 months ago and I still have the problem. I also reverted to an earlier image for the XP computer and that doesn't solve it.
For many years I never had these problems with the Win7 PC and 2 XP PCs. My problems started when I got the Win 8.1 Pro PC to replace one of the XP PCs. I'm wondering if this problem has something to do with the Win 8 computer, which is my main work computer, so it's difficult to revert to a very old image for it, simply because I'd have to spend a lot of time installing lots of programs and doing tweaks. I hope I can solve the problem without doing something extreme.
Recently I found that the Win 8 computer was set to public network, but I changed it to Private network. Unfortunately that didn't solve the problem. Any suggestions on solving this issue?
