Quick Fix for Unknown Error 0×80072f78

My device started to complain about some unknown error today, when i was trying to browse the internet when connected via USB cable (other connection methods works well). The solution is pretty easy!

According to this article this is actually a problem with Layered Service Provider:

If you are using ActiveSync 4.2 and have a problem with Desktop Pass-through it may be caused by a Layered Service Provider (LSP) that use the Windows TCP/IP stack. This has been known to occur with ISA Server. The registry file LSPValue.reg will reverse this setting. Microsoft and the Pocket PC OEM does not support users that edit the registry.

The LSPValue.reg file contains:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services]
"AllowLSP"=dword:00000000

Download the file (by right clicking it and selecting Save as…) to your desktop and doubleclick it to import it to the registry. Remember that changing your registry settings can be dangerous. You are doing it at your own risk!
