DTM Setting

When I try to connect DTM server from DTM studio running on WinXP, I got the following error message:
error: 40 - Could not open a connection to SQL Server

Solution:
In client machine ( which DTM studio is installed)
Type: c:\windows\system32\cliconfg.exe

Open NamedPipe and TCP/IP from the options.

If this doesn't work, check if NamePipe and TCP/IP is open on the DTM server settings
