Last week my servers lost power, and now every night the DC seems to get demoted. The only event errors I receive are File Replication errors. Due to low disk space on my root partition. (2GB free currently) I haven't had these issues before with lower disk space so I wouldn't think this is the issue. I fixed a DNS issue as well, deleting an incorrect DNS record pointing to the wrong FQDN name. I have tried resetting my LAN to no avail. This is a solo DC, do I need to demote then promote this controller?
