Article ID: 170661

Article Last Modified on 11/4/2003



APPLIES TO

  • Microsoft SNA Server 3.0
  • Microsoft SNA Server 3.0 Service Pack 4



This article was previously published under Q170661


SYMPTOMS

After you upgrade from SNA Server 2.11 Service Pack 1 (SP1) to SP2 (or SNA 3.0 or 3.0 SP1), a TN3270E printer emulator may be unable to get a printer session through the TN3270 server. The TN3270 server reports Event 902 to the Windows NT application event log, indicating an LUSessionStateConfused error in the InboundLULUData function.

CAUSE

The TN3270 server is expecting 3270 data by checking for DT_3270_DATA (screen data) but is ignoring valid DT_SCS_DATA (print data).

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 2.11 Service Pack 2 (SP2) and 3.0 SP1. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack.
