SYMPTOMS
When you log on to Windows Terminal Server using the RDP client, you may receive the following error message:

NetDDE Services:

Another user or machine has the same name as this account on the network. Network DDE services will not be available.



CAUSE
This message appears if someone else is logged on with the same user name. The error message means that Network Dynamic Data Exchange (NetDDE) programs, such as Microsoft Chat, cannot function because, if someone wants to chat with you, there is no way to know which user to contact.



RESOLUTION
Log on to each computer with a unique user name.



STATUS
This behavior is by design.



MORE INFORMATION
The NetDDE service on Terminal Server registers with the user name instead of the computer name. This is necessary because all network clients that use the Terminal Server will have the same computer name.
