Is the server a SBS 2008 server? If so, I suggest you confirm if Windows Small Business Server 2008 Update Rollup 3 is installed. Description of Windows Small Business Server 2008 Update Rollup 3 Also you may manually check your SRV records on the server. If the records are incorrect, please refer the following article to resolve the issue.
