INFO: Connection Limitations in Non-Enterprise Version of MSMQ

• Microsoft Message Queue Server, version 1.0
• Microsoft Windows NT Server, version 4.0

SUMMARY

In the future, Microsoft Message Queue Server (MSMQ) will be available for use on a Windows NT Server Standard Edition 4.0 platform.

Some restrictions to this version of MSMQ have been identified. This version of MSMQ will have a maximum of 25 client connections to the server.

That is, when an MSMQ Independent or Dependent Client connection is requested to an MSMQ server, MSMQ will compare the Windows NT Server Standard Edition 4.0 available Client Access Licenses (CALs) with the MSMQ maximum connection limit of 25 to determine whether the connection should be allowed. MSMQ will use the smaller of the two numbers as the connection limit to the server.

For example, on a computer running Windows NT Server with a connection limit of 15, MSMQ will allow only 15 connections to the server. On a computer running Windows NT Server with a limit of 100 connections, MSMQ will allow 25 connections to the server.

MORE INFORMATION

The version of MSMQ that comes with Windows NT Server 4.0 Enterprise Edition is limited only by the number of available Windows NT Client Access Licenses.

You can use the Licensing icon in Control Panel to find the number of authorized CALs for a server.
