I have a workgroup that consits of a few XP machines and one windows 7 laptop. They are all connected via ethernet; no wireless. I put all my information in the Shared Documents on the Windows 7 machine for the XP users to access. On all the XP machines, I have a shortcut to the desktop that goes straight to the Shared Documents on the 7 machine. What has been happening is every few days an XP machine here and there will lose connectivity to it; the shortcut wont work per say. In order to get it to work again, I have to manually direct to the IP address or DNS name of the Windows 7 machine, or even reboot the thing. Its getting tedious and I wonder what the issue can be. I'm thinking theres a connection lost in the Windows 7 laptop periodically, but then it comes back online. I just want to make sure if theres something on the software side that I can set up or verify is set up correctly before I move on to a networking or hardware issue.
