Microsoft has issued an alert over connection problems with the latest edition of its ActiveSync mobile software.
The advisory warned that some common PC programs will cause synchronisation problems between PCs and mobile devices.
The issues occur when USB connections are attempted and range from total failure connecting a PC to a smartphone or PDA device, to dropped file transfers and partial synchronisation only.
"In some specific cases, Windows Mobile device connectivity to a Windows PC running Microsoft ActiveSync 4.0 may experience connection problems," said the company.
"[The problems] are probably caused by interoperability with desktop firewall applications or applications that manage network traffic. These applications appear to conflict with the TCP traffic between a device and the PC."
Most popular firewall software products are cited in the advisory, including products from Zone Labs, McAfee, Symantec, Trend Micro and Sygate. The problems are only with USB and do not affect radio connections via Bluetooth.
Microsoft has included a workaround for the problem in its advisory and will be issuing a new version of ActiveSync in November.

Actvesync Not doing what it says on the label
I have similar problems, two computers, and neither will sync with my new Pocket PC running Windows Mobile 5.0. I have downloaded the modified Active Sync 4.1,which improved slightly, allowing me to sync once only after installation, and then failing to re-connect when a second attempt is made to connect up. Its a bit of a drag having to un-install and re-install 4.1 every time I connect my Pocket PC. By trial and error, i have found that I can only sync if the Zone Alarm Firewall is switched off even though Zone Alarm is correctly set to enable Active sync to operate, so why cant I sync correctly? Does every Firewall conflict with Microsoft Active Sync?
