Hello all!
I hope someone can help us with our issue.
We are running Windows 2012 Datacenter on a Host. The guest VM is running 2012 as well. Over the past couple weeks we have been having an issue where the guest that is the AD controller just freezes up. Sometimes we are RDP'ed into it and open the start menu to do something and other times no one is logged in but all the folder shares, RDP, etc goes unavailable.
We thought it had to do with the backup system. But the backup isn't running at the time of the freezes. Today we had 2 seperate times that the AD server froze up once in the morning and it affected the other guests so we had to power cycle the host. Then in the afternoon I caught it soon enough to where I could shut the other guests down. When I went to try and shutdown or reset the AD guest it just stated shutting down.. So I ended up having to power cycle the host again.
The event log doesn't show anything in the host or the guest..
We have disabled write caching on the host to hope this will help but we are getting to a loss.
Host system specs are as follows:
Windows 2012 DC
Dual Quad Core Xeon's
72GB Ram
2 x 500GB RAID 1 config through the OS
2 x 4TB RAID 1 config through the OS
We are planning to purchase an iSCSI storage array in the next couple weeks but are afraid it won't fix the issue..
Thoughts?
