Connection for Downstream PU Fails to Reactivate After Outage

• Microsoft SNA Server, version 3.0

SYMPTOMS

A downstream connection fails to activate after an outage even though both stations are ready.

CAUSE

If SNA Server received a reactivation XID while it was processing the outage, it would set the link in a state from which it could not reactivate. The connection would have to be manually reset for it to reactivate.

NOTE: This article is related to the following Knowledge Base article, which documents a similar (but not identical) issue for SNA Server version 2.11:
