SYMPTOMS
The Microsoft Exchange Server 5.5 message transfer agent (MTA) may fail to maintain a connection over a DRAS connection. Events similar to the following may appear in the Application event log:

  Event: 1294 Source: MTA An association with entity /O=MICROSOFT/OU=THEFORCE/CN=CONFIGURATION/CN=CONNECTIONS/CN=DAGOBAH TO  PLEASUREDOME ended abnormally. [4 1 0 0 PLATFORM KERNEL 16 130] (10)

Event: 9316 Source: MTA An RPC communications error occurred. No data was sent over the RPC connection. Locality table (LTAB) index: 4. Windows NT error: 1783. The MTA will attempt to recover the RPC connection. [BASE IL PIPE RAS 24 230] (12)



CAUSE
The Windows NT error 1783 in Event 9316 equates to "Bad Stub Data." This problem occurs when the number of messages in the outbound DRAS connector's queue exceeds the DRAS connector's configured threshold. By default, the Threshold value is set to 50. When the queue exceeds this threshold, an additional association is generated. However, the sending MTA passes an invalid context handle to the receiving MTA, which terminates the connection because the handle is invalid.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.5. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.5.
