Chapter 4 Without the Hotfix
If the Windows Terminal Server is not configurable with the hotfixes listed in Chapter 3, the
resulting Terminal Server functionality of no configurable option for multiple TCP transport
sessions renders the Samba server default configuration behavior incapable of starting more than
one smbd user process. Thus, the single smbd must service all incoming client connections from
a particular Terminal Server, resulting in potential performance degradation.
Levels of performance degradation (if any) are entirely dependent upon user load and
environment variables. Heavy client processing can exhibit noticeable degradation with only 2
Terminal Server users. However, user feedback has proven that some installations have run as
many as 100 Terminal Server clients on a single smbd, with adequate performance (this level of
usage is not recommended). This particular usage scenario experienced a non-performance
resource limitation, which is addressed below.
The single smbd process servicing multiple users and associated IDs will correctly handle
switching permissions and access rights for shared resources on the Samba server.
Potential workarounds to Terminal Server integration issues are identified in the next chapter.
