Windows Mobile 6 PDA won't sync unless Windows Firewall service stopped
Our head's PDA(Windows Mobile 6.5) HTC Diamond HD2 was sent back to be fixed. I've spent ages trying to get it to work with ActiveSync but have failed every time even though it used to work.
I had a look at the Windows XP SP3 Firewall exception settings:
Everything is ticked for ActiveSync except for "ActiveSync service" which is greyed out and cannot be ticked. It says No under the Group Policy column. I've tried to change as the Administrator too.
The phone will only sync when the "Windows Firewall/Internet Connection Sharing (ICS)" service is stopped in Control Panel.Administrator Tools.Services.
