Host Sends Logon Screen Before RUI_WRITE Completes on Open

• Microsoft SNA Server, versions 2.0, 2.1, 2.11, 2.11 SP1, 3.0

SYMPTOMS

In some cases, the mainframe may send the logon screen down before the RUI_WRITE on the Open has completed. If this occurs, the RUI_WRITE for the response to the logon screen fails.

CAUSE

A timing issue has been identified that allows the host to send the logon screen to the client prematurely.

RESOLUTION

To resolve this problem, obtain the hotfix mentioned below. In the hotfix, Winsli32.dll has been modified so that it does not issue RUI_READ for the SSCP normal flow until RUI_WRITE has completed.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SNA Server versions 2.0, 2.1, 2.11, 2.11 Service Pack 1, and 3.0. This problem was corrected in the latest Microsoft SNA Server 2.11 and 3.0 U.S. Service Packs.
