Netdde.exe Does Not Relay WM_DDE_TERMINATE to Remote Clients

ID: Q231337

The information in this article applies to:

Microsoft Windows NT Server versions 4.0 SP4, 4.0 SP5
Microsoft Windows NT Workstation versions 4.0 SP4, 4.0 SP5
Microsoft Windows NT Server, Enterprise Edition versions 4.0 SP4, 4.0 SP5

SYMPTOMS

When a remote client in a Dynamic Data Exchange (DDE) conversation with a server computer running Windows NT 4.0 Service Pack 4 or 5 sends WM_DDE_TERMINATE to the server, Netdde.exe does not relay the server's WM_DDE_TERMINATE response back to the remote client.

In addition to causing the client to never receive WM_DDE_TERMINATE, this also has the undesirable effect of leaving child windows orphaned.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or the individual software update. For information on obtaining the latest service pack, please go to:
