We hebben een Server 2012 R2 draaien die ineens een system failure aangaf en automatisch herstarte.
De logs nagelopen en kwam DNS issues tegen.
Event viewer:
--------------------
The dynamic registration of the DNS record '_ldap._tcp.Default-First-Site-Name._sites.ForestDnsZones.domain.local. 600 IN SRV 0 100 389 srv-dc.domain.local.' failed on the following DNS server:
DNS server IP address: ::
Returned Response Code (RCODE): 0
Returned Status Code: 0
For computers and users to locate this domain controller, this record must be registered in DNS.
USER ACTION
Determine what might have caused this failure, resolve the problem, and initiate registration of the DNS records by the domain controller. To determine what might have caused this failure, run DCDiag.exe. To learn more about DCDiag.exe, see Help and Support Center. To initiate registration of the DNS records by this domain controller, run 'nltest.exe /dsregdns' from the command prompt on the domain controller or restart Net Logon service.
Or, you can manually add this record to DNS, but it is not recommended.
ADDITIONAL DATA
Error Value: Bad DNS packet.
The WinRM service failed to create the following SPNs: WSMAN/srv-dc.domain.local; WSMAN/srv-dc.
Additional Data
The error received was 9502: %%9502.
User Action
The SPNs can be created by an administrator using setspn.exe utility.
[b]DCDIAG DNS TEST:
----------------------------
Directory Server Diagnosis
Performing initial setup:
Trying to find home server...
Home Server = srv-dc
* Identified AD Forest.
Done gathering initial info.
Doing initial required tests
Testing server: Default-First-Site-Name\SRV-DC
Starting test: Connectivity
......................... SRV-DC passed test Connectivity
Doing primary tests
Testing server: Default-First-Site-Name\SRV-DC
Starting test: DNS
DNS Tests are running and not hung. Please wait a few minutes...
......................... SRV-DC failed test DNS
Running partition tests on : ForestDnsZones
Running partition tests on : DomainDnsZones
Running partition tests on : Schema
Running partition tests on : Configuration
Running partition tests on : domain
Running enterprise tests on : domain.local
Starting test: DNS
Test results for domain controllers:
DC: srv-dc.domain.local
Domain: domain.local
TEST: Basic (Basc)
Warning: no DNS RPC connectivity (error or non Microsoft DNS server is running)
srv-dc PASS WARN n/a n/a n/a n/a n/a
......................... domain.local passed test DNS
------------
In de DNS staat deze ldap record wel geregistreerd.
Alles lijkt verder ook gewoon normaal te functioneren.
Het lijkt erop dat de server iedere 2 uur een storing hierop krijgt en zich reboot.
Ik heb nog niets kunnen herleiden waar dit in kan zitten
