After restart of win server 2008 R2 have a problem with DNS role. On DNS I see that primary domain zone is not introduced and there is red cross.
If I look to log I see some ID 4004, say that DNS cannot get information from active directory. Check active directory.
So I check active directory but not see any errors.
So I look again to event Viewer - server DNS: there is a error: "DNS Server encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. Advanced debug error information (which may be empty): 000020EF: SvcErr: DSID-02060237, problem 5012 (DIR_ERROR), data -1017. The error is stored in the data block of the event."
Now I have switched to another DNS.
What I can do? I was wondering to remove and instal DNS role. Can any one give me advice?
Thanks A lot
