Exchange 2003 ActiveSync Not Working

We are trying to get ActiveSync working on a single server Exchange 2003 setup.  The MS Remote Connectivity Analyzer (www.testexchangeconnectivity.com) is giving the very common HTTP 500 error and we have applied the recommended fix of creating a new virtual directory without SSL required.  We have used the AccessMyLan (www.accessmylan.com) tools to test ActiveSync internally and we get the same HTTP 500 error, so it doesn't look like a firewall issue (ISA2004), but an Exchange issue.

All research shows that the HTTP 500 error should be resolved by creating a new virtual directory with SSL not required.  Before I created this I was getting Event 3029 in the App Log as detailed in KB817379, since making the change I am not getting that error.

Hoping we can get this resolved without logging a case with MS.

Thanks,

Nick

Thanks alanhardisty, that has fixed it!  Changes I made from your guide were changes to network binding order, removed required SSL on Exchange vdir in IIS, enabled HTTP keep-alives.  Not sure which one did it, didn't think I needed to remove the SSL requirement on the vdir as I had created a new vdir without SSL required and made the reg change to point to this.

Anyway, it's working so many thanks and points to you :)
