Problemas posteriores al SP3

Colegas..

Realice la actualización del SQL con SP3 y a partir de ese momento los
uusarios de un sistema no pueden ingresar a realizar un INSERT

Todos los usuariso son simples ususarios de la red de W2K

la seguridad del SP es por intregracion con el Windows.

personalmente asigno los permisos necesarios al grupo que puede realizar la
actividad.

pero me devuelve este error. Y ocuure desde la actualizacion del SP3.. antes
todo funcionaba muy bien

Alguien tiene idea de que puede pasar...

Agradezco su ayuda --
Les dejo el mensaje de error

Saludos
