The maximum number of simultaneous, active requests between an SMB client and the server is determined when a client/server session is negotiated. The maximum number of requests that a client supports is determined by the
MaxCmdsregistry value. The maximum number of requests that a server supports is determined by the
MaxMpxCtregistry value. For a particular client and server pair, the number of simultaneous, active requests is the lesser of these two values.
In a BizTalk environment, add both registry values to the BizTalk server and the remote UNC Share server.
To track the number of simultaneous, active requests on an SMB client, add the Current Commands counter in the SMB Redirector performance object to Performance Monitor.
