Frozen Queues Detected
Topic Last Modified: 2006-05-03
The Microsoft® Exchange Server Analyzer Tool queries the ExchangeLink Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the StateFrozen key for the Simple Mail Transfer Protocol (SMTP) queues on a server.
If the Exchange Server Analyzer finds that the value of the StateFrozen key for any one of the SMTP queues on an Exchange server is set to True, the Exchange Server Analyzer displays an error.
A frozen queue means the transport sessions for that queue are stopped. A frozen queue prevents outgoing messages, although new messages can be added. You can manually change the state of a connection by using the shortcut menu on each link queue. When you use the Force Connection command to change a queue state to Active, you immediately enable a connection that sends the messages from that queue.
For information about the particular SMTP queues that are affected and the possible cause, see the following Exchange Server Analyzer Tool articles:
