RDP Client Hangs If the Network Is Unavailable

ID: Q187183

The information in this article applies to:

Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When network connectivity is not available and the Microsoft Terminal Server Client (MSTSC) utility is connected, the computer may stop responding (hang) for approximately two minutes when you disconnect the MSTSC utility.

CAUSE

The MSTSC utility displays the Connect dialog box and makes a NetServerEnum call to enumerate the servers. Before the enumeration completes, if you click Cancel or press ESC, the dialog box disappears. But the MSTSC utility waits for the NetServerEnum call to complete before terminating its process. This process may take as long as two minutes. If you wait for the NetServerEnum call to complete before pressing ESC, the process terminates immediately.

RESOLUTION

The NetServerEnum call is a synchronous call; there is no way to cancel it to avoid the delay.

STATUS

This behavior is by design.
