I tried all the things Les said, but still I have the ame
problem. Everything works fine, until I re-start the
server. Then, all the ports in RRAS disappear! To get
them back I have to un-install ISA, re-start the server
and re-install ISA. Each re-start of the server therefore
takes between 30 - 45 mins!

Please please can someone else give me any clues. Its
really starting to get to me!

Thanks in anticipation.

Joel
