SUMMARY
The network protocol used between a client and a server during a Remote OLE
Automation Session depends on whether a prior connection still exists
between the two computers. Subsequent connections to that server depend on
the protocol used for establishing the first connection to that server, if
this first client makes a call to the server that returns another object.
MORE INFORMATION
If Client1 uses the TCP/IP protocol to connect to Server1 and calls a
method on an object1 (in Server1) that returns an object2, a new connection
will be established between client1 and object2 of Server1 that also uses
TCP/IP. Now, if a client2 connects to server1 using the IPX protocol and
calls the same method on object1 that returns it an object2, a new
connection will be established between client2 and object2 of Server1 that
uses the TCP\IP protocol, even though the original connection for client2
used IPX.
If the first connection between client1 and server1 is severed before a
connection is made with client2, the new client2 connection that is
established on returning object2 would now use the IPX protocol.
