We need to carry out a abrupt shutdown/restart test of both domain controllers and clients/switches etc. When I do that (after abrupt restart) 1) I can not login to domain from client PC (both DC’s are fully up). I found that I can not ping by hostnames (any system). 2) From PDC -> AD Users & Computers -> Connect to BDC. The error is the following domain controller cannot be contacted…. the server is not operational The only way to resolve this issue is again rebooting the domain controllers gracefully. What is causing this issue? Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
