How many aggravating hours have you taken to get your Windows Mobile device 
synced up to your PC and watched and listened to the connection wizard go boop, 
boop, boop, and never connect? What is going on here? 
  Well I'll tell you.  ActiveSync uses TCP/IP ports for connection.  And most 
new Antivirus products are coming with a built in firewall, not to mention the 
good old Windows XP Firewall (which already knows about these ports, yay).  
  Turns out that the ActiveSync processes use the following ports which need to 
be open in your firewall application:

  If these ports are not open.. No tickie, no workie, no sync.
  Here is a link from Microsoft page on troubleshooting your ActiveSync 4.x 
connectivity and my pick for the week:
  I found this out when we upgraded our network to the new version of Trend 
Officescan which snuck in it's own firewall service and our directors telephone 
all of sudden stopped syncing.  After several maddening hours of reinstalling 
activesync, getting a new phone and cradle and still not working, I had to 
count back the hours and figure out exactly what changed. Didn't figure for 
trend to throw that curve at us but you live, you learn.
