To fix the DNS functionality try this steps, first try to rest the DNS cache:<\/p>\n
net stop netlogon\r\nnet stop dns\r\nDNSCMD ServerName \/clearcache\r\nAfter that, please rename the following two files  located in the Windows\\System32\\Config:\r\n1) netlogon.dmb to netlogon.dmb.old\r\n2) netlogon.dns to netlogon.dns.old\r\nThen, please run the following commands:\r\nnet start netlogon\r\nnet start dns\r\nipconfig \/registerdns<\/pre>\n
Test the dns with nslookup :
\n<\/strong><\/p>\n
from the CMD run nslookup \"Your DC Name\"  or nslookup google.com<\/pre>\n
If that didn’t work try reseting the WMI repository, First run:<\/p>\n
winmgmt \/verifyrepository<\/pre>\n
If the repository is in a consistent state I would recommend to stop and look for another solution how ever to reset the repository you can try :<\/p>\n
Winmgmt \/salvagerepository<\/pre>\n
That will take the content of the inconsistent repository and merge it into the rebuilt repository if it is readable, If this failed the try :<\/p>\n
Winmgmt \/resetrepository<\/pre>\n
*. I have seen cases thet the WMI service can not be stopped, pausing the service will help as well \ud83d\ude42<\/p>\n
That will reset repository to the initial state when the OS was first installed . More information about resetting the WMI can be found here<\/a><\/strong><\/p>\n
Then reboot the server !<\/p>\n

Good Luck<\/h3>\n","protected":false},"excerpt":{"rendered":"
