Error 0x80072F17

I am using SBS 2003 with Exchange Service Pack 2 installed. I have a user with a PDA running Windows Mobile 5.0version. This PDA is able to sync through a cable with a desktop computer properly but it fails with error 0x80072F17 if I am trying to sync with the server, either via a cable over the lan or through the phone network. I think that this error is certificate related and I have disabled SSL on the PDA and require secure channel is disabled on IIS\server\websites\default website\Microsoft-Server-ActiveSynch Directory Security Secure Communications. Now, if the PDA is trying to sync then I am getting prompted for the username or password.
