Latest interesting moment with SCVMM 2012 R2 is really interesting.
Have a vmm environment with multiple hyper-V hosts. some hosts are named custhv01, custhv02, etc. When adding another ccusthv01 and ccusthv02 the original hosts got “access denied”. After renaming the newly added hosts to custhv-01 och custhv-02 and reassociate the old host we got all working again. I have no idea why it did not work, but my guess is that there is a “-match” somewhere in the dcvmm-code.
