Currently running MS Windows 2003 Server Enterprise with Exchange 2003 Enterprise with all service patches. I have setup rpc ove http works great love it. I have a Sonic wall and have open ports to allow mobile device to sync with exchange. I was setting up one in my lab for test run. I purchased the Sprint PCC-6700 with MS CE 5. When I try to setup the active sync to hit the exchange I recieve an error on the device of 0x85010001. I have done some reseach on google and made the registry change for active sync. I still can't get this to connect. I know it is passing by the firewall so ports are correct.
