Using Windows Terminal Server as a client to the z/OS SMB server

When a PC connects to the z/OS® SMB server, each PC usually has its own communications session to the z/OS SMB server. See Figure 1 for an example.
Figure 1. SMB server with a single user session on each communications session
In the Windows environment, each individual PC has its own session with the SMB server on z/OS.
When the Windows Terminal Server is used by a PC, multiple PC users connect to the Windows Terminal Server. They see another entire Windows system screen in a window of their local PC. This window represents applications running on the Windows Terminal Server machine. If the PC user issues a net use command inside that window, that net use command will actually be executed on the Windows Terminal Server machine. The Windows Terminal Server machine can create multiple user sessions (one for each Windows Terminal Server client) on a single communication session to the z/OS SMB server. See Figure 2 for an example.

In a multiple-user environment using a single communications session, each PC goes through a Windows Terminal Server before reaching the SMB server.
