Exchange 2003 ActiveSync doesn't want to work,

We have a new Windows 2003 SBS Server with Exchange 2003. Whenever one of our new Motorola MPX200 smartphones tries to connect to the exchange server to get ActiveSync info, I get :

Synchronization failed due to an error on the server. Try again.
Error code: HTTP_500

I have tried the solutions below, and nothing seems to work (see links at bottom). I have tried mucking around with the permissions in IIS myself to try and solve the problem, but I am afraid I have no idea what is actually required by ActiveSync for it to work. We are doing this on the local network (through "passthrough" mode), so it definitely is not a firewall issue. The user that I am trying to log in as can use OMA and OWA just fine. We are trying to get another "server ActiveSync" device in here to make sure it isn't a problem with the phones (although that error message makes me think it is a problem with IIS). This is really frustrating, anyone have any luck getting their SBS 2003 server to talk ActiveSync? What are your permissions/authentication types on all of your ActiveSync related folders in IIS? Any help would be appreciated!

We did step 7 (we have a local certificate) on the phones.
We did step 17 as well, but after going through all of the Sharepoint related fixes it turns out Sharepoint is not "extending" the IIS server so you can't do the "exclude" procudere listed here (step 2), we did however set up Sharepoint to use Kerberos:

I turned off SSL on all of the IIS folders as well.
