MSTSC V6, both in XP and Vista, now asks for credentials EVERYTIME you connect! I want the server to ask, not the client! Add this line to the Default.rdp file located in your My Documents folder.
enablecredsspsupport:i:0
Also:
authentication level:i:0
You may need to save as another name, then
rename the Default.rdp and replace the file.
