I've just installed SMS 2.0\SPK4 on my new Windows 2000 site server. The remote control agent works on some workstations and servers but not on others. When I try to start remote tools on a workstation, it says, remote control agent not found. I've tried updating the site configuration via the Systems Management Icon in the control panel but it fails to update the site configuration for this workstation. The systems that I'm trying to remote control does appear in the collection all systems query.
