After Downgrading from ActiveSync 4.1 to 3.8 you can only connect as Guest when attempting to synchronise

Applies To:

• HPC2000
• Windows CE .net 4.0, 4.1, 4.2
• Windows CE 5.0

Overview:

After downgrading from ActiveSync 4.1 or 4.0 to ActiveSync 3.8.5004, when you attempt to synchronise your device, you can only connect to the Windows CE Service Communications manager process in the guest account.

More Info:

You may experience the inability to mount a partnership if the ActiveSync 4.1 installation leaves behind a Registration Utility Library in the System folder on your PC.

NB: If you require instructions covering the process of reverting to ActiveSync 3.8 from a 4.x client, see CESDS0093.

To restore Partnership Synchronisation you must delete the Windows CE Reigstry Utility Library from the System Folder

1. Uninstall all ActiveSync versions from your computer
2. Open My Computer
3. Navigate to:
   c:\windows\system32
   -or-
   c:\winnt\system32
4. Locate and delete the file
   ceutil.dll
5. Reinstall ActiveSync 3.8.5004
