winsock errors 10054 and 10053 during ActiveSync attempt

[Clark Wilson]

My ActiveSync 4.5 synchonization with a Windows Mobile 6 device spontaneously
went bad soon after unexpected building power loss and power restore events.
The PPC syncs okay with another, nearly identical laptop. The same ActiveSync
error message occurs whether I am synching via cable or via Bluetooth. The
laptop is XP Pro SP2 with security patches applied.

My most recent Bluetooth attempt ended with this sequence of messages (from
WCESCOMM.LOG):

Do these messages point anyone to a diagnosis and fix? Is there another
newsgroup better suited to this question?
