This is a general error but here's where I ran across it.
On a network running SBS 2K3 R2 we were troubleshooting use of IPv6. We had it working on another server and one thing we did was compare installed updates. On the functioning server an update named "Windows Small Business Server 2003 R2" was listed. So we reinstalled the R2 technologies on the non-working server.
Then came the problems, first RPC via HTTP stopped working. After finding that RPC was disabled and enabling it (did not fix the issue) the Active Sync issue appeared.
The solutions was to enable Integrated Windows authentication on the exchange-oma virtual directory.
- Open IIS
- expand to Web Sites\Default Web Site
- right-click exchange-oma and choose properties
- click the Directory Security tab
- click the Edit button in Authentication and access control
- check the Integrated Windows authentication box
- click OK twice
