windows server 2008 r2
This morning 1/2 of the computers on the domain are unable to access the DC. network connection shows Domain connection shows as “unauthenticated”.
I have gone into AD and right clicked on the computer and clicked reset in hopes of resetting the connection without losing the SID. now when the user tries to login, she receives the error: "the trust relationship between this workstation and the primary domain failed".
On another computer I tried to remove and re-add to the domain and receive the error " An Active Directory Domain Controller (AD DC) for the domain “x.x.com” could not be contacted
DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "(domain).COM":
The query was for the SRV record for (domain)
The following domain controllers were identified by the query:
However no domain controllers could be contacted.
Common causes of this error include:
- Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses.
- Domain controllers registered in DNS are not connected to the network or are not running.
1/2 of the computers are working, I'm afraid of messing with any server settings at this point...
On Friday, we updated our SSL certificate, other than that nothing has changed... Also, I can access the server via IP address but not name on the machines that are down... Not the most familiar with the DNS settings in the server.
