I had this issue once before and with an uninstall of lights-out, registry clean, reboot and re-install of Lights-Out, it was fixed. But this time it's not working. When Lights-Out sends the server to hibernate, all is well. But when it wakes the server, it boots into what appears to be a boot hang. After further investigations, I found that the IP address of the server during this hang is 'MININT-XXXXXXX'. That led me to find that the server is stuck in a Win PE environment (pre-installation). This is the 2nd time this has happened in 2 months and seems to coincide with Windows Updates.
On this second time I can't resolve my problem by a uninstall/clean/re-install. Please help. I don't think there's any log files referring to the error, as the server never actually boots.
