Our company has just started using Windows 8. We have a domain controller on our network. When adding to the domain from a local windows 8 account, it says we are added. When trying to logon to the domain using proper credentials, we receive the error: "There are currently no logon servers available to service the logon request." I have tried changing registry settings for the cached accounts, I have tried changing group policies, nothing is helping. We do not have this problem on Windows 7 or Vista.
