Error 18452 Login failed for user <null>. The user account is not

We have a SQL 2005 installation using SQL and Windows Authentication. We
have a login that is mapped to a active directory group and has the
appropriate permissions to the database. However, when we try to create
an ODBC connection to the server from an XP client (and the user is a
member of the appropriate domain group) we get the above mentioned error.
Also logged on the SQL server is the following error:
SSPI handshake failed with error code 0x8009030c...
The only info I can find on this error has to do with IIS
configurations, but I don't see what IIS has to do with this as we are
only trying to make an ODBC connection.Maybe your service account is Local System.
You can change to AD Service account.
