How long is a piece of string?
The OOB Server for NT can run in 2 configurations.
The default is to create a new thread for every incoming ODBC connection. The server under this configuration requires about 2Mb and approximately 250K per thread but this latter number starts at 250Kb and rises depending on what you do with the ODBC driver you are connected to.
An alternative configuration for non-thread-safe ODBC drivers instructs the OOB Server to start a new process per connection. This requires approximately, 2Mb for the main server and 2Mb+ for each connection.
