I had a problem with a user who couldn’t mount a network drive.  When I would attempt to add the drive manually, I got the error “The drive could not be mapped because no network was found“.

Sitrep:

• Network was working (symptoms occur on both wireless or wired)
• Fileshare mounting WAS working (it would  mount another network drive on the same server, also it mounted redirected folders on the same server just fine)
• Can not browse windows network
• Workstation service was running fine

I mention the last one because this knowledgebase article explains that it’s a problem with the windows Workstation Service.  I would buy this if I couldn’t mount ANY folders or network drives, but the service seems to be running and restarting it doesn’t affect anything.

My Solution:

1. Go to “Network Connections”
2. Right click a network connection, go to “Properties”
3. Highlight “Client for Microsoft Networks”
4. Click “Uninstall”
5. Restart computer
6. Go to “Network Connections”
7. Right click a network connection, go to “Properties”
8. Click “Install”
9. Select “Client for Microsoft Networks”
10. Click through dialogs
11. Restart

This worked perfectly for me.  The network drive mounted right up afterwards and my problem was solved.  Let me know in the comments if this worked for you or if you are stuck somewhere!
