Will recently had a client who could not connect the client workstation to the server workstation in V10 and here is how he fixed it:
After looking at all of the normal things, he found that a Windows update had turned off the public file sharing in Win7. In Win 7, you need to make sure that network discovery and public folder sharing are both turned on. These options can be found in the Network and Sharing section of the control panel.
Once we corrected the permissions issue, we were still not able to connect. We then switched back to single user mode (a new feature in V10 found in the file menu) and switched back to multi-user. Problem fixed.
