No NMVT for Printer DDDLUs After Connection Outage

After a connection outage, SNA Server and Host Integration Server 2000 may not reactivate any printer Dynamically Defined Dependent Logical Units (DDDLUs).

Display DDDLUs and Logical Unit Application (LUA) DDDLUs do not exhibit this problem.

After the connection outage, the SNA Server service does not send a Network Management Vector Transport (NMVT) command for the printer DDDLUs to solicit an Activate Logical Unit (ACTLU) command from the remote computer.

For additional information about an earlier fix for printer DDDLUs, click the following article number to view the article in the Microsoft Knowledge Base:
The earlier fix corrected the NMVT problem only when a DACTPU command was received from the host before a connection outage. In situations where no DACTPU command is sent from the host before the connection outage, and in situations when an ACTPU type cold is received from the host system, the NMVT problem still occurs. The fix in this article now corrects the NMVT problem in these additional situations.
