VMs disappearing from Admin Console

-

i have noticed of wsus clients running server 2k3 ent on vms periodically disappear admin console.  if go 1 not showing , run wuauclt /resetauthorization /detectnow, show in console, 1 of vms disappears.  have identified 2 machines seem teeder-todder , forth.  both clients appear configured correctly.  identifies them admin console seem overwrite 1 another?

this typical behavior of duplicated susclientids, guid identifies client wsus server, , typically caused unhealthy system cloning procedures. since we're talking vms, i'll venture guess of vms built same parent vhd, , should -- applied of updates parent vhd before cloning it. unfortunately, it's susclientid of parent vm that's being cloned of other vms.

in registry key hklm\software\microsoft\windows\currentversion\windowsupdate
delete susclientid , susclientvalidationid values
and restart automatic updates service.

the next time machine executes detection generate new guid , report wsus server.

the permanent fix delete susclientid , susclientvalidationid parent vhd before shutting down , marking vhd readonly.

Edit Group Policy

i have pc has power settings pushed out default domain policy in ad environment. of course on local machine "some settings managed system adminstrator". the machine temporarily no longer in contact domain controller (it's been physically moved , not on same network now) can't updated gpo settings. i believe if edit local group policy won't make difference because of group policy processing , precedence. since it's temporary away ad network, still want use settings of ad user. is there somewhere in registry stored can edit power plan manually until can sync domain? (i need prevent sleeping while plugged in - it's set 1 hour) thanks! allen crist i found site: http://gpsearch.azurewebsites.net/#7916 i able add policy to hkey_local_machine\software\policies\microsoft\power using specs found on site. looks solved issue. i'll report if didn't. thanks! allen crist ...
