XCON: DRAS Failing after You Upgrade to Windows NT 4.0 Service Pack 4

• Microsoft Exchange Server, versions 4.0, 5.0, 5.5
• Microsoft Windows NT Server, Enterprise Edition version 4.0 SP4

SYMPTOMS

The Dynamic RAS Connector may fail to transfer mail after you upgrade to Microsoft Windows NT Server version 4.0 Service Pack 4. The dialing server receives the following event and is immediately disconnected:

Event ID: 20082
The account for user %1\%2 connected on port %3 does not have Remote Access privilege. The line has been disconnected.

Category: Interface
An interface error has occurred. An MtaUnBindBack over RPC has failed. Locality Table (LTAB) index: 73, NT/MTA error code: 1783. [BASE IL MAIN BASE 5 519] (14)

WORKAROUND

There are two workarounds:

• On all servers that are initiating the connection:
  
  
  1. Start the Exchange Server Administrator program.
  
  
  
  2. In the left pane, click the Connections object, and in the right pane, double click the Dynamic Ras Connector to be modified.
  
  
  
  3. Click the RAS Override tab, and specify an account other than Service in the Connect As portion.
  
  
  
  The alternate account specified must have Service Account Admin permissions on the remote Exchange Server computer.



• Copy in Rassapi.dll from a Windows NT Service Pack 3 installation to the Winnt\System32 directory.

MORE INFORMATION

Dynamic RAS fails to transfer if the account specified on the Override tab is called Service. The problem has been known to occur when you dial computers running Windows NT Server that have been upgraded to Service Pack 4.

After the upgrade is complete, accessing the Service account through the RAS Administrator interface yields the following error message:

Error 6: The handle is invalid.
