Hi Jake, Thank you for the post. Have you changed any configurations on DNS server recently? Please check via "ipconfig /all" and "dcdiag /fix" command and post the results for analysis. Here is article about troubleshoot DNS event 4000 & 4015. http://social.technet.microsoft.com/wiki/contents/articles/2063.dns-stops-working-on-windows-server-2008-dns-event-id-4000-4015-and-userenv-event-id-1053-1054-dsforum2wiki.aspx If there are more inquiries on this issue, please feel free to let us know.

I've just had an issue arrise that I cannot seem to solve. I recently set up a Windows Server 2008 DC with DNS and DHCP and all has been working fine, but I discovered today that when I go into the DNS Manager I get the following issue: DNS. Access was denied. Would you like to add it anyway? I choose the option to connect to the local computer as that is where the DNS service is running, and I have tried using the FQDN with no luck. The DNS services have been restarted with no effect, and I have tried adding the Administrator group to the DNSAdmins group but this didn't help either. Also I changed the ACL for the DNS object in the Active Directory Users and Computers to give Administrators full access but this didn't help either. The domain isn't fucntioning properly as a result, with slow logins now and new GPOs not being pushed. (I'm assuming as the Windows 7 clients cannot map the server name with the IP maybe?) I've checked the Event Log for the DNS and these are the most common errors: 1) The DNS server was unable to open Active Directory 2) The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error. Any suggestions would be appreciated. Thank you, Jake Server 2008 R2 - error code appears to be 4000.

You are an absolute hero! The host file had the two configuration lines hashed out so they weren't in operation. Thank you!
