Don't know if this is your problem, but there was a bug a while ago in SQL
Server 2000 to do with the introduction of Kerberos aware authentication
using DBLibrary connections over TCP/IP.

IIRC, the SQL Client and SQL Server would not correctly negotiate packet
sizes. This could be circumvented by explicitly overriding the default
packet size in the client app. This was resolved in SQL Server SP2.

Kind Regards, Howard
