When I offline or online a service group, the group becomes frozen immediately, and I am also having trouble bringing the group up and down. If I online/offlilne each resource manually it seems to work, but the group gets "stuck" at certain places when brought online/offline all at once. For instance it cannot offline an IP address (should happen in less than a second) or deporting a disk group. My dependencies are set up correctly, and it's a very simple service group. The engine log says "VCS monitoring set to 'Freeze' mode" which I cannot find anywhere else in the world.
