My OS array is full of windows installer files over 30 gb with 3.5 gig free space. I dont want to extend it past the 2 drives it is on into the storage array. Is there a way to fix this without causing problems with windows installer? Its not completely full but its screwing with my failover making the target full. It appears that MSIZAP is possible solution but according to the documentation it will possibly screw with windows installer. Some folks say that visual studio caused the problem. Why it was installed on the DC is beyond me. Any help or suggestions would be appreciated.
