Terminal Server Clients Cannot Connect For the First 15 Minutes After License Server Is Available (234324)



The information in this article applies to:

  • Microsoft Windows 2000 Server

This article was previously published under Q234324

SYMPTOMS


When a Terminal Services client tries to connect to a server, it may be denied a connection for up to 15 minutes.

CAUSE

This issue may occur when the client tries to use terminal services after the 90-day license server grace period has expired.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Windows 2000.

MORE INFORMATION

A terminal server can provide unlicensed client sessions for 90 days from the day when the first client makes a connection. After the 90-day period a terminal server must be able to connect to an activated license server to verify the existence of a valid license.

The discovery of the license servers on the Terminal Server takes place on a separate thread at 15 minutes intervals. This discovery process is independent of the client connections and the results are cached.
Whenever a client tries to establish a connection, the name of the license server is retrieved from that cache.
With enforced licensing (after the 90-day license server grace period), if a terminal server needs a license to allow a connection, and the license server has only recently become available, the client may have to wait for up to 15 minutes for the discovery thread to discover the license server.
