VS2005 Remote Debug connection problem

I got error message when trying connecting to remote debugging machine using
Visual Studio 2005's Attach to Process, it said "Unable to connect to the
Microsoft Visual Studio Remote Debugging Monitor named 'machine_name'. The
data area passed to a system call is too small."

I've been following Microsoft instruction at
http://support.microsoft.com/kb/910448 and successfuly connected using Native
only with no authentication mode. But no luck with Windows Authenitication
mode, I tried both machine_name and Domain\User@machine_name format in the
Qualifier field to no avail. These two machines are in the same domain and I
have admin rights.

Has anyone experienced this problem?
