Renewing Your Internal Certificate

MSMQ dependent clients, independent clients, and servers can renew their internal certificates (used for authentication) using MS Message Queue in Control Panel. You should renew you internal certificate when you:

• Rename your computer
• Remove your computer from one site and install it in another site
• Remove your computer from one enterprise and install it in another enterprise
• Log on as more than one domain user under Windows 95

Windows 95 clients can specify which network should be their primary logon network (using Network in Control Panel). If you choose Windows Logon as your primary logon, Windows caches passwords you specify for network resources. If you send authenticated messages and log on to a Windows NT Server domain as more than one domain user, you must renew your internal certificate each time you log on as a different user.

For more information on renaming a computer running MSMQ, see "Renaming a Computer Running MSMQ" later in this chapter.

1. In Control Panel, double-click MS Message Queue.
2. On the Security tab, click Renew Internal Certificate.
A warning appears stating that undelivered messages that you have already sent using the current internal certificate will be rejected as not authentic.
3. If rejecting those messages is acceptable, click Yes.
Or, if it is not acceptable, click No and renew your internal certificate some other time.
