SYMPTOMS
If the host tries to start an outbound bracket while an RUI application is in the middle of sending a chain that comprises a single bracket (BBI = BB, EBI = EB), the RUI library subsequently rejects the negative response sent by the application in response to the SDI message generated by the SNA Server with a return code of RESPONSE_REQUIRED.



CAUSE
This is due to SNA Server internally changing state to In Bracket during reception of the chain.



STATUS
Microsoft has confirmed this to be a problem in Microsoft SNA Server 2.0, 2.1, 2.11 and 2.11.sp1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
