The TCP/IP network protocol. The APPX client uses TCP/IP to communicate with APPX Presentation Server.

If the client is a Windows 95 machine, and you EVER anticipate sharing the network drive containing the APPX application data files and running appx.exe (not appx -c) at the client with APPXPATH set to that network drive, you MUST install the Windows 95 network file redirector fix provided by Microsoft at

        http://support.microsoft.com/support/kb/articles/q148/3/67.asp 

to avoid the potential for APPX data file corruption due to a bug in Windows 95. If you don't do this now, you may forget to do it later, corrupt your data files, and spend hours on problem resolution and recovery. You would not be the first person it's happened to. You have been warned.

        NOTE ABOUT URLs:  Microsoft periodically rearranges its web
        site, so the above URL may or may not be valid.  If you can't
        find it, use the "Search" option on the MS web site, instructing
        it to look in whatever choice includes the "Knowledge Base".
        Specify "Qnnnnnn" as what to look for, where nnnnnn is the number
        between the "q" and the ".asp".  For example, in the above, it
        would be Q148367.  That should enable you to locate the article.
