Have found this problem as well. No changes with SIM, just installed the Support Pack 8.00.
As an added bonus, now getting lots of application error report popups on the console from wmiprvse.exe, faulting module HPWinHostedEthernetTeam.dll, version 2.1.0.0. To the tune of dozens per day.
I will be trying to revert back to 7.91. Everyone should be advised that 'upgrading' to version 8.00 software is not a good idea!
