Remote Desktop Disconnected (error 50331656)

I have a home-based Windows 7 remote client that has been using Remote Web Workplace (RWW) to connect to his office Windows 7 client system through SBS2008 for several years without trouble. Suddenly, his remote connections are crashing with the error 50331656. He can maintain a remote connection anywhere from 3 to 25 minutes before crashing and can immediately reconnect after re-establishing the connection.

I have used another Windows 7 remote client to login to the same user account and connect to the same target Windows 7 client and can maintain a stable connection for at least 100+ minutes. This remote client has never had a remote connection failure.

The problem started right after the last set of Windows Updates from Microsoft on 3/11/15. But I have also uninstalled all of those new updates from the home-based client and the problem remains.

This is getting frustrating for both me and the user. Any ideas on cause are appreciated.



Set up a new, test Windows User Account (User Profile). Log in to the new profile and test Remote Desktop in the new profile. It could be a damaged profile.

Try scanning for viruses with your own application and then Malwarebytes.

Try running System File Checker. Run SFC /SCANNOW and allow to complete. Restart and test to see if SFC repaired the issues.

Have a look at the solution in a previous question posted on EE: http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Q_24840841.html

Although the symptoms aren't exactly the same, I have seen reports of that particular registry fix resolving the issue for a number of other people.



@ John Hurst - Thanks for your fast response! Setup a new user account profile, scanned system with Vipre & MBAM, and ran SFC /SCANNOW. All scans were clean. No change in connection failure with new profile.

Any other ideas?



@ VB_ITS - Thanks for responding with your suggestion. The certificate entries to be deleted from the Parameters registry key do not exist. So they cannot be deleted.

Any other ideas?



If the scans, System File Checker and new User Profile did not solve the problem, then you need to run Windows 7 Repair Install. For this, you need a working recovery partition or the Windows 7 DVD. Here is a Seven Forums tutorial to assist you with this.

If you prefer and not a lot more time, back up, format and reinstall Windows 7.
