Problems with ActiveSync after update

[apperrault]

Greetings all,
For some reason, after i did the update, my ActiveSync is no longer working. It was working just fine before the update. I am the network and email administrator, and i havent changed anything, but when i try to initiate the sync, it gives me an error 0x80070057. Has anyone else had this problem. I am getting ready to go on vacation for a week, and i really need to get this working again.

Thanks much
