I use netdde in excel to get data from a netdde server.
The spreadsheet works in terminal server sessions on NT4,
and works on the windows2000 console, but simply fails to
getdata if run in a windows2000 terminal services session.

Any ideas?
 
Hi Paul

There's an issue when you use NetDDE in a TS session because of the way TS handles network computer IDs. You should check your TS documentation, since each TS session is identified by the user id only and not the computer name, as required by NetDDE (which uses NetBIOS to locate computers on a network). Since you can have multiple active sessions on a single TS server, TS does not identify the machine name when accessing a DDE remote node and therefore the NetDDE request cannot be serviced. I don't know if there's a workaround for this issue, because it is imposed by TS "by design"
