I upgraded to 4.5 yesterday and I am getting Auth: Fail when connected through activesysnc 4.5 and docking station. If I disconnect from the station and connect through wifi I have no problems.

Any hits?

Update I can't even use IE when it is docked. I must have something not set correctly.

Fix for unknown error 0x80072f78
While trying to browse the internet on my x50v while cradled using ativesync 4.2 i recieved the following error " The page you are looking for cannot be found due to unknown error 0x80072f78 "

fumbling with the settings did nothing, DELL support "unofficially" pointed out a registery fix for this issue that fixed it perfectally for me and i thought i would pass it along.

#23 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.

Windows Registry Editor Version 5.00
