I maintain a small network for an accounting office. My client has a Windows 7 Professional server which is sharing Internet access and sharing a folder to 2 Windows 7 workstations and 2 Windows XP workstations. I have the folder mapped as drive "L:" on all the workstations.
Everything works fine for the Windows 7 workstations. They are able to access the Internet and read/write files in the shared folder all day, every day.
Everything works fine for the Windows XP workstations at first, but then they lose access to the shared folder after awhile (sometimes hours, sometimes overnight). They retain access to the Internet, however. I am sometimes able to reboot the Windows XP workstations to see the shared folder again, but other times the connection just comes and goes at an apparently random schedule.
Here's what I've done to try to address this. Some of these seem unrelated to my problem, but I'm desperate for a fix.
- All workstations and the server are on the same workgroup.
- Password-protected sharing is enabled on the server and all workstations and the server have the same user names and passwords.
- Firewalls are properly configured (using Windows firewall which MS says is automatically configured when you turn on sharing) and turning off firewalls doesn't fix the problem.
- The network on the shared side of the server is set to "Work" (although it is an "Unidentified network" because I don't have a router installed).
- Advanced properties on the server are set to "Enable NetBIOS over TCP/IP" (it had been "Default")
- The server is my workgroup's master browser.
- Power saving on the server's network cards is turned off, so they never power down.
I have looked and looked for the solution to this, but haven't found it so far. I thought it would be related to the firewall or the master browser, but I haven't found that to be the case so far. Please let me know if you have any other ideas. Thank you in advance!
