I have SBS 2003 with activesync and it was running flawlessly for a few years untill a few days ago we changed the IP address of the server. Now everything works (exchange, OWA, BES, etc) except activesync. I did the test at testexchangeconnectivity.com and it failed on this:
Validating certificate trust for Windows Mobile Devices
Certificate trust validation failed
The certificate chain did not end in a trusted root. Root = CN=Equifax Secure Global eBusiness CA-1, O=Equifax Secure Inc., C=US
The ONLY thing that has changed was the IP address of the server. It's an actual bought SSL cert which must still be working because my exchange accounts are still using it. I've combed EE and tried others that have simmilar problems, I've even deleted the cert and re-installed it.
What am I missing? How can the cert be invalid now because of an IP change and only for mobile devices?
