Windows Mobile 5 or 6 Activesync Internet Pass Through

If you had problem connecting to the internet via activesync on Windows Mobile 5 or 6 or simply get a 0x80072f78 from Pocket IE, I found a solution here:

1. 1. Open Registry Editor on your desktop (Start/Run and type "regedit") and locate the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows CE Services.
2. 2. Right-click on the value list and choose New/DWORD value. Type the name "AllowLSP" and leave the value zero.
3. 3. Disconnect and connect your device and Pocket Internet Explorer (and all other applications) will start working.
