error 0x20b5/8373 when registering a SPN

We recently delegated permissions to register SPNs to a network administrator. When he tried to register a SPN using setspn, he got this message:

error 0x20b5/8373 The name reference is invalid

We found the solution quickly: He was providing an invalid SPN (the error message could be a little clearer)...
Instead of doing HOST/Servername he had used HOST\Servername

To summarize: When you get this error, make your SPN is correct regarding syntax etc.
