Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 2.
Note that the Terminal Services Advanced Client Readme.htm file incorrectly states that this issue is resolved in Windows 2000 Service Pack 1 (SP1). The following text from the Terminal Services Advanced Client Readme.htm file is incorrect:
3.1 Terminal Services Connections Snap-in Might Cause MMC to Fail During Frame Resizing
There is a known problem with the Microsoft Management Console in Windows 2000 whereby certain snap-ins, such as the Terminal Services Connections snap-in, can cause the MMC to fail under certain conditions. This can happen if the system focus is on the Terminal Services Connections snap-in, and you attempt to resize the MMC frame (that is, move the splitter bar that separates the contents pane from the topic pane). Upgrade to SP1 to resolve this issue.
