Hi Dave101010,
Since when are you facing this issue?
Do you remember making any changes to your computer?
The problem is with the computer because the connection can break even if the host computer freezes and that is the reason why you are not able to login physically on the host computer.
I suggest that you put the Host computer in a Clean Boot and check for the issue. Below are the steps to put the computer in a Clean Boot State:

Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.<br><br><br>5. Click OK.<br><br><br>6. When you are prompted, click Restart.<br><br><br>7. After the computer starts, check if the issue is fixed.<br><br><br>If your issue is resolved after performing Clean Boot, then follow the steps mentioned in the following KB article to narrow down the exact source:<br><br><br>http://support.microsoft.com/kb/929135 <br><br><br><br>Also, see the section on how return your computer to a Normal startup mode by following the steps under “Reset the computer to start as usual”, after<br> performing the clean boot troubleshooting |
