Not sure. Try using v6.2 and
http://www.visualbuild.com/Manual/programremotetab.htm
If that doesn't help, please ZIP and send or post:
1) The info from Help | About | Install Info
2) The Windows version+SP of the remote computer
3) A reproducible test case (.bld file that can be built here and reproduces the problem)
4) A build log file
Thanks.
