Clients Running MS-DOS

By default, Microsoft Exchange Client uses the following RPC binding order for MS-DOS when attempting to connect to a server:

  1. Local RPC
  2. Named pipes
  3. SPX
  4. TCP/IP
  5. NetBIOS

You can change the RPC binding order for clients running MS-DOS after you have installed MS-DOS. To change the order, edit the RPC_BINDING_ORDER line in the Mlsetup.ini file. This file is installed automatically on the client or on a network share. For example, the following entry in the Mlsetup.ini file attempts to establish local RPC, named pipes, TCP/IP, and NetBIOS connections in the order indicated. 

RPC_Binding_Order=ncalrpc,ncacn_np,ncacn_ip_tcp,netbios
