Crash while repair on Windows

[vikarti]

Situation: Deep check was started from WUI on windows node(Windows Server 2008R2 if that's important). I manually deleted some random shares in storage on one of other nodes(running Mac OS X if that's matter) and after that - stopped that other node.(I was checking how it will react to HDD failing)

Suddenly windows node's MUI deep check went to:
