so what My question is on a more serious note. I have a active directory domain Server running a server 2012 forest type. What i am looking for serious input regarding is one of my core servers in the domain running data center 2012 and primary roles are hyper-v remote instance (session host) , application service host and iis. so she has active directory lightweight ds installed. and does not provide a primary domain controller role. so with that info and downtime being as low as possible, i have some kind of virus, im pretty sure it is running somwhere with the internet explorer. internet explorer freezes nomatter what domain or user account is signed in with. What is a registry utility that can be used in a way to not run into any configurations after repair? Connectivity to the server domain is becoming a issue. yet locally or via different subnet you can manually add other servers in the domain to the group. But does not find a current domain that that is joined. There are other issues and factors that lead me to somthing blocking ports or forwarding registry values. its hard to tell threw analyzing debugs with the amount of traffic from users.
