One of the DC's in my firm ran out of space on the C$ after running recent Windows updates. The DC is running Win svr 2008 R2
I tried to extend the size of the C$ but despite having 177gb of unallocated space the option to extend is greyed out for some reason!!
The D$ on the same server is no longer required so I was going to delete the D$ and extend the C$ but the option to delete the volume is greyed out. Please advise the best way to proceed.
