RESOLUTION
WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them.
Microsoft cannot guarantee that any problems resulting from the use of
Registry Editor can be solved. Use this tool at your own risk.
To enable support for NetBeui over the Dynamic RAS Connector, the following
registry adjustment will need to be made on both Microsoft Exchange Server
computers.
- Start Regedt32.exe and open the following key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Exchange\Exchange Provider
- On the RPC_SVR_BINDING_ORDER registry entry add the following value:
NCACN_NB_NB
Make sure this setting is entered on both Microsoft Exchange Servers so
that they will have a common protocol. After the change is made, stop and
re-start the MSExchangeMTA service.
It is important to note that the MTA reads the RPC_SVR_BINDING_ORDER in a
serial manner, so the placement of the protocols can effect how the MTA
functions. If the NCACN_NB_NB value is first in the order, the MTA will
attempt to use NetBeui first. If it is last, the MTA will read through
all the other values sequentially. What this means is that if NetBeui and
TCP/IP are both loaded, and the NCACN_NB_NB value is last in the binding
order, TCP/IP will be used. This is only important in environments where
there are mixed protocols and/or adapters.
CAUTION: Using only the NetBeui protocol with the Microsoft Exchange
Dynamic RAS Connector may cause delays in modem disconnect times with
certain modems and/or telco line conditions. This is due to a limitation
in the NetBeui protocol. If such symptoms are encountered, we recommend
that an additional protocol such as TCP/IP also be installed.
