SUMMARY
A Dynamic Remote Access Service (RAS) connection configured with override account information may not authenticate. Consequently, the servers cannot bind over remote procedure call (RPC), and may generate the following events:

Dialing Server

Event ID 9318

An RPC communications error occurred. Unable to bind over RPC. Locality Table (LTAB) index: 5, NT/MTA error code: 1722. Comms error 1722, Bind error 0, Remote Server Name SREX [MAIN BASE 1 500 %10] (14)

The following events are written to the system log:

Event ID: 5719

Source: Netlogon

Type: error

No Windows NT Domain Controller is available for domain CRM. (This event is expected and can be ignored when booting with the 'No Net' Hardware Profile.) The following error occurred:

There are currently no logon servers available to service the logon request.

Event ID 9322:

An interface error has occurred mta bind back over rpc has failed locatility table 108, mta error: 1722 1722 bind error 0, remote server name... protocol string id-tcp:ipaddress of server.

9316

An RPC communications error occurred. No data was sent over the RPC connection. Locality table (LTAB) index: 4. Windows NT error: 0. The MTA will attempt to recover the RPC connection. [BASE IL KERNEL 26 512] (12)



MORE INFORMATION
There is empirical evidence that supports that servers handling Dynamic RAS connectors be Windows NT backup or primary domain controllers. Member servers handling Dynamic RAS connectors add an extra step of querying the domain controllers for account validation. This extra step can add additional overhead, which prevents the connection from being established, so that mail flow cannot occur.
