DNS Server is crashing periodically RRS feed

  • Question

  • Hello.

    We have 3 servers with AD and integrated DNS Server, 2 Windows Server 2012 and 1 Server 2008.

    The DNS Server on this 3 servers is crashing in random times and we need to manual start the service (services.msc).

    It started when we migrated two servers from 2008 to 2012...

    Any tip to fix it? Bellow the log that we get when the problem happens:

    Faulting application name: dns.exe, version: 6.3.9600.19292, time stamp: 0x5c5dd0f4 Faulting module name: dns.exe, version: 6.3.9600.19292, time stamp: 0x5c5dd0f4 Exception code: 0xc0000005 Fault offset: 0x00000000000a5633 Faulting process id: 0xe48 Faulting application start time: 0x01d5632d8e8337bf Faulting application path: C:\Windows\system32\dns.exe Faulting module path: C:\Windows\system32\dns.exe Report Id: 644ff44a-d0b0-11e9-80d7-005056981fc7 Faulting package full name: Faulting package-relative application ID:

    And

    The DNS Server service terminated unexpectedly. It has done this 1 time(s). The following corrective action will be taken in 120000 milliseconds: Restart the service.

  • Are you saying on all three this happens? If so its likely a configuration error of some sort. I'd start with running;

    • Dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
    • repadmin /showrepl >C:\repl.txt
    • ipconfig /all > C:\dc1.txt
    • ipconfig /all > C:\dc2.txt
    • ipconfig /all > C:\dc3.txt


    then put unzipped text files up on OneDrive and share a link.

  • Domain controllers should be limited to a single ip address. Multiple addresses will always cause no end to grief for active directory DNS. If routing to other networks is required then use appropriate layer three hardware.

  • You suggest to set a single IP address on DC Servers or set a single IP for DNS listener? 

    Also, dcdiag show this message:

  • You suggest to set a single IP address on DC Servers


    Yes, set a single static IPv4 ip address on each of the domain controllers. Then if problems persist put up a new set of files.

  • Hello.

    Did you have a doc or something that talk about the problems using multiple ip address on Windows Domain controllers?

    Its because another guy is responsible for our dns server....

    Monday, September 23, 2019 1:43 PM
  • Sorry about delay to answer... Yes, problem still happens. 

    In all this three servers the dns.exe is crashing.

    Have you removed the extra IPv4 addresses?

  • Still no. We need a time because the extra IP address is used as DNS Server in some other hosts...
    Monday, September 23, 2019 2:07 PM
  • Sounds good then. Should be a very easy and quick fix to clean it all up. Also this script may be helpful

    or many more you can find here.
