Master server is Win2003 Std Ed SP1, and NBU is v6.0 MP1, with BMR
installed. In workgroup mode, not a domain.

Everything was working fine, and then after four days, when I click on "BMR"
at the bottom of the left hand panel in the Admin Console GUI, I get a popop
stating "An invalid argument was encountered", and I can no longer manager
BMR via the GUI. BMR still works from the command line, though - and all
other Admin Console functions are fine too.

Any ideas?
