Not sure that I can help, but I'm not clear on what you are telling me.
Your host is running Server 2008 with Hyper-V. Fine. Got that. Are you telling us that the host is also running DNS, DC, and BE? And that those aren't in guests? And that when it goes to back up a guest the host reboots? Regards, Michael B.

It's also a DNS server, a DC, and a Backup Exec server. Its function as a backup server is new-I've only been doing that for about two days. Twice today, while backing up one of the VMs to a NAS system, this server has rebooted. I've backed up the other VMs with no problems, but this one VM (our Exchange VM, incidentally) seems to cause a problem. I'm really not sure how to troubleshoot a spontaneous reboot with Server 2008. The event logs show nothing (other than an entry after the reboot saying that the shutdown was unexpected). The reliability monitor shows nothing-no crash or anything. It's basically like what would happen if I just unplugged a server's power. Power problems are unlikely, though, as this server has dual power supplies, and each is connected to a separate UPS.
