This is the socket used to communicate to the SNA Server service. 0x05C6 - Socket used to support SNA Server client "sponsor sessions". This is the socket used to communicate to the Snabase service over which the client workstation receives a list of other SNA Servers running in the domain. The SNA Server client socket number is allocated dynamically through the Windows Sockets interface. In addition to TCP/IP protocol over Windows Sockets, Microsoft SNA Server version 2.1 clients use the following to communicate with the server: - Named pipes (over any local area network [LAN] transport supported by the Microsoft network redirector included with Windows for Workgroups, Windows NT, or LAN Manager) - NetWare IPX/SPX - Banyan IP (over Banyan Vines) - AppleTalk The third-party products discussed here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
