the user group did not have “Access this computer fromt the network”.
I saw this by opening “Local Security Policy” in Administrative tools.

The SQL Server Network Interface library could not register the Service Principal Name (SPN) for the SQL Server service. Error: 0x2098, state: 15. Failure to register an SPN may cause integrated authentication to fall back to NTLM instead of Kerberos. This is an informational message. Further action is only required if Kerberos authentication is required by authentication policies.

However, none of them were useful for me. In my development environment I had been using a connection string which used a DNS name (Host A record, as a matter of fact) pointing to the IP of the server where SQL 2005 is installed.

After trying several things, I finally went to the web.config and changed the connection string to the server name. After this, I got another message: Login failed for user ‘NT AUTHORITYNETWORK SERVICE’. [CLIENT: ]

I had seen another article saying to give this user access to the data base under User Mappings and after that all worked like a charm.

Hope this is helpful for anyone.

I found that this error was caused by users who’s password had expired and had decided not to change it. Although they remained logged in and were able to operate on the network. When connecting from one SQL server to the next, kereberos was unable to pass their authentication details.

Once we reestablished connectivity to the Domain Controller, the error stopped.
