I have a smal win2k3 small business server. it crashed becasue of low disk space. I was able to extend partion and reboot but I have a black logon screen. I was able to find a fix for the black screen but it involves modifyinf the registry of the DC. Since i cannot see anything i nee to modify from a member server no other DC/BC's exist on network. Is it possible and if so how?
