SYMPTOMS
The Microsoft Systems Management Server (SMS) versions 1.2 and 2.0 Remote Control function does not allow multiple remote control sessions of Microsoft Windows 3.1 and Windows 95 on client computers running SMS 1.2 client software. This is because of an internal limitation of the NetBIOS protocol and also, in part, because of a NETBIOS and TCP/IP protocol conflict.



CAUSE
SMS 2.0 is designed to support up to four remote control sessions on different client computers when all connections are using TCP/IP. When NETBIOS is used for remote control sessions, the SMS Administrator console can connect to and initiate remote control sessions on only one computer at a time.

As long as the remote control protocol is configured to use TCP/IP only, any Administrator console is able to initiate remote control sessions on up to four computers simultaneously. However, as soon as one of the computers needs to use NetBIOS, the number of available sessions is limited to one.



STATUS
Microsoft has confirmed this to be a problem in Systems Management Server version 2.0.



MORE INFORMATION
When the first NetBIOS session is established, the special NetBIOS name  (padded to 15 characters) is obtained for the session (  refers to the viewer). When a second session is attempted, even on TCP, a NetBIOS connection is attempted regardless, because the system tries all known protocols. However, the  name cannot be obtained.
