Install Failed, rolled back... but in Windows the client appears fine and dandy.

working with a 2008 R2 enterprise server.

What would cause this machine to show up in the SEPM with a issue icon (little arrow and the red X) and state the install was failed, rolled back, but the client once i log into it is running SEP with a green dot and no visable issues to speak of. I tried deleteing the object from SEPM but when it re-populates it is no different.

Any suggestions besides reinstalling it? I can't reboot this server until Friday night when i get a maint window.

thanks all and happy Monday.
