I am able to successfully sync my Cingular 8125 to my home computer.
When I bring it to my office and plug my phone in, it gets itself to
the point where it says "Syncronizing" and then it just hangs there
indefinitely.

My problem was with the desktop. but appararently it would be about the same
for the server.
It seems that this guy http://www.sb.com.au/jasjar/activesync_4_0.html had
solved this problem. I tried it myself and it worked for me ! - thank you

I've got an O2 Atom, its syncs with my work laptop W2K, used to sync with my
W2K PC. Recently upgraded to XP Pro SVC 2, no longer works on the PC.
When I tried to Sync Pda, windows device manager tries to install it as
"Windows Mobile based device". Install fails, message ...
