I am running to some dns problems every 21 days.
When i run a dcdiag /test:dns i get the following results (i will put the full log later on)
Summary of DNS test results:
Auth Basc Forw Del Dyn RReg Ext
serverdc2 PASS FAIL PASS PASS WARN FAIL n/a
......................... domain.local failed test DNS
After a dcdiag /fix everything works fine again.
DNS Scavening is set to every 7 days but after 21 days we receive this error.
There are 2 domain controllers, serverdc1 is the primairy server and serverdc2 is the secondairy.
Does anybody had any idea why this is happening every 21 days.
some other errors in the log :
Domain Controller Diagnosis
Performing initial setup:
* Verifying that the local machine serverdc2, is a DC.
* Connecting to directory service on server serverdc2.
* Collecting site info.
* Identifying all servers.
* Identifying all NC cross-refs.
* Found 2 DC(s). Testing 1 of them.
Done gathering initial info.
Doing initial required tests
Testing server: domain\SERVERDC2
Starting test: Connectivity
* Active Directory LDAP Services Check
The host e3a31358-75b4-41b4-886d-8660f088e000._msdcs.domain.local could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
(e3a31358-75b4-41b4-886d-8660f088e000._msdcs.domain.local) couldn't be
resolved, the server name (serverdc2.domain.local) resolved to the IP
address (**.**.**.**) and was pingable. Check that the IP address is
registered correctly with the DNS server.
......................... SERVERDC2 failed test Connectivity
Thanks for the help!
