Any windows event ID's related to this? These might be handy. 
I suggest you read : http://www.scomgod.com/?p=155 

On the SQL server, to add the SPN, use: 
setspn –A <SPN> <Account>
Example: setspn -A MSSQLSvc/SCMVPSCOM01.test.COM:1433 TEST\SVCACCOUNT

Does the SQL server has an A and PTR record in the DNS? Do verify that.

And there is bit more explained .

I think these should help you to fix this.
