Hosted Apps connection problems – Windows XP SP3 with RDP 7 client installed / KB969084

Please note Windows XP is no longer a supported operating system. If you are still using Windows XP you should upgrade or replace your computer ASAP.

If you have version 7 of the Remote Desktop Client installed on a Windows XP machine you may have problems connecting to the Scomis services from a school outside of SWGfL – ie Portsmouth, Oxford.

To check if this is the root cause of the problem:

  1. Click Start > Run
  2. Enter mstsc.exe – click enter
  3. Right Click on the title bar then choose about
  4. RDP Client 7 will show as

See the last line “Remote Desktop Protocol 7.0 Supported

  1. Enable CredSSP following the kb or using this Microsoft Fixit:
  2. Save this registry fragment  ScoCredSSPSettings.reg onto the computer, rename it to .reg
  3. Merge it into the system
  4. Restart the computer
  5. Try connecting again


If after trying the registry fix you get a different error message saying:

“connection terminated because an unexpected server authentication certificate was received from the remote computer”

Then you will need to remove RDP7
