You might have a port issue on your firewall too. From the Microsoft KB
article 259369
ActiveSync requires the following Winsock Transmission Control Protocols
(TCP) to be available: . 990
. 999
. 5678
. 5679
If socket port filtering occurs on any of these Winsock ports, ActiveSync
does not synchronize with Windows CE-based devices

Hmmm? I've tried everything both of you suggested, and still Sygate must be
blocking something that ActiveSync requires, because ActiveSync tries for
about 10 seconds and then reports it cannot connect. With the Firewall off,
it connects instantly, so I must be doing something wrong.
I am going to have to find someone with more knowledge of this issue than me
to resolve it.
Thanks for your help.

Is there a spot in there that lets you declare specific networks as OK? When
AS connects via USB it sets up a little network with the PPC being
192.168.55.101 and the PC having a virtual IP of 192.168.55.100. Can you set
the firewall to allow the 192.168.55.x network?

Does this page or any of Chris' related pages help you? I know he covers
this specific topic as well as issues introduced by Windows SP2 and a host
of other hairy issues.
