XCLN: Creating Roving Users on MS-DOS Client

MORE INFORMATION

To create an environment where Microsoft Exchange client for MS-DOS users can access their mail from any computer on the network, administrators must run the following steps:

1. Create server based home directories on the network for each roving user and assign logon scripts that will automatically connect the user to their home directory.
2. Run the Microsoft Exchange Client for MS-DOS Setup program and select the Shared installation option.
3. Update each user's Windows NT logon scripts with the following lines:
   

         SET EXCHANGE=H:\ 
         SET RPC_BINDING_ORDER=ncalrpc,ncacn_np,ncacn_ip_tcp,ncacn_spx,netbios
   						

   
   where H:\ is the path to the user's home directory on the network. Depending on the protocols installed on the network, you might need to modify the RPC Binding Order.

Each user will then need to run the following steps to complete the installation process:

1. Log into the Windows NT domain and connect to the share point where the Microsoft Exchange client for MS-DOS has been installed by the Administrator.
2. Run the Microsoft Exchange client for MS-DOS Setup program and select the Workstation installation option. When you are prompted to modify the Autoexec.bat file, select the option NOT to modify the file. This would conflict with the information in your logon script.

Each user should now be able to go to any workstation, connect to the share point containing the network installation of the MS-DOS Exchange client and run Exchange.exe to bring up the Microsoft Exchange client for MS-DOS. The user's mail will always be on the Microsoft Exchange Server based store because the Microsoft Exchange client for MS-DOS does not permit local .PST files.
