I am advising someone on how to disable TCP Chimney Offload, which is enabled by default by Windows Server 2003 SP2. We are working in an environment with multiple server machines, namely the application server machine which communicates with the database server machine.
This can cause communication problems between application and database. See KB942861 and Windows Scalable Networking Pack - Possible Performance and Concurrency Impacts to SQL Server Workloads.
On which machine should TCP Chimney Offload be disabled? Application, database or both?
