Yea, it's intermittent. I've moved off Windows 7 for any test cases and just on Ubuntu now. So far it seems a bit more stable. One issue I did find, diff topic and a new thread perhaps, is the ICS for Windows 7 blows and jacks up the Jasager with them both fighting for authoritative DHCP. No issues on Ubuntu for any of the tests I've done so far for this. Thanks for the replies.
