Clients Running Windows and Windows for Workgroups

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

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

You can change the RPC binding order for clients running Windows and Windows for Workgroups before or after you have installed Microsoft Exchange Client.

Before installation In Setup Editor, select the Binding Order property page.

After installation In the Exchng.ini file in the Windows directory, edit the [Exchange Provider] section. For example, the following entry in the Exchng.ini file attempts to establish SPX, TCP/IP, and NetBIOS connections in the order indicated. 

[Exchange Provider]
RPC_Binding_Order=ncacn_spx,ncacn_ip_tcp,netbios
