I've got a 64-bit Server 2008 machine running Hyper-V. 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. Any pointers? ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
