Here is a quote from an article that discusses that and was found through www.eventid.net
I am quoting one section from that page.

Bugs in Windows 2000 DDE

Connecting to an instance specific service does not work, an internal system error is reported. If more than one instance of an application is running you cannot connect to a specific one, unless the server application itself distinguishes between instances on the basis of the topics supported. For example, Excel supports topics based on the workbook and sheet name.
There is a bug which may prevent a NetDDE connection from working. Details are in the Knowledgebase article Q272485 NetDDE Client Is Unable to Connect to NetDDE Server on First Attempt. Microsoft claim that this bug is fixed in Service Pack 2.
The article Q181946 HOWTO: Create a NetDDE Client and Server in Visual Basic, contains a workaround for a bug in DDESHARE. When you trust the share, you must select "Initiate to Application Enable" and click the "Set" button before clicking OK on the two dialogs.
It is necessary to set the DSDM service to Manual start. The NetDDE service may be Automatic or Manual, it starts DSDM itself. It was suggested by Microsoft to a reader of this page that allowing DSDM to start automatically can cause NetDDE not to work, and we have confirmed this.
