If you have a Palm Treo 700w or Audiovox XV6700 [both from Verizon], you might face the problem of Activesync stuck at connecting even though a Windows Mobile based device network adapter would show up under Network Connections/Device Manager of your computer and all anti-virus/firewall software being disabled. The reason this may be happening is Wireless Sync which comes preinstalled on Verizon phones may disable the Activesync connection. To check do the following:

On the Windows Mobile device, go to Start—–>Programs——>Wireless Sync.

There should be a tab Activesync Setup with 3 options for Enable Activesync Connection:

1) Ask each time
2) Disable
3) Enable

Choose the Enable Option. And Voila! you should be able to synchronize!
