When you apply the post-Exchange Server 5.5 Service Pack 3 (SP3) hotfix, or Exchange Server 5.5 Service Pack 4 (SP4), the Message Transfer Agent (MTA) may not start and you may receive a 2140 error message. The following errors may be reported in the application event log:
MSEXCHANGEMTA 9321 An RPC communications error occurred. An attempt to listen over RPC has failed. NT Error: 11004. [ BASE IL MAIN BASE 1 504] (14)
MSEXCHANGEMTA 9266 A fatal system error occurred while initializing the MTA. Reboot the computer. If that does not work, contact Microsoft Technical Support. [4 BASE IL MAIN BASE 1 173] (16)
MSEXCHANGEMTA 9406 There is not enough Performance Monitor memory to display the MTA Connections information. Stop attached Performance Monitors and re-start the MTA. [BASE MAIN BASE 1] (14)
To resolve this issue, make sure that the internal network adaptor is the first item that is displayed in the binding order:
Quit any programs that are running.
Right-click Network Neighborhood, and then click Properties.
Click the Bindings tab. In the Show Bindings For box click All Services.
Double-click each listed service to expand it.
Under each service, move the internal network adapter to the top of the binding order.
In the Show Bindings For box, click All Protocols.
Double-click each listed protocol to expand it.
Under each protocol, move the internal network adapter to the top of the binding order. The final order should be similar to:
Network adapter one
Network adapter two (if present)
Remote Access wide area network (WAN) Wrapper
After you have verified that the bindings are set correctly for all services and protocols, click OK. Rebinding then occurs.
Click Yes when you are prompted to restart the computer.
This behavior has been observed on servers that have more than one network adapter.
