goes down then everthing stop working

I'd check the DHCP server is handing out other domain controller IP's as alternate DNS to the problem members.




@Dave Patrick 

1) the dc are statically assigned and none of them point to this dc including itself.

2) check dns server nothing is pointing to this dc


None of that makes any sense.

Please run;

  • 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
  • (etc. as other DC's exist)
  • ipconfig /all > C:\problemworkstation.txt

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






@Dave Patrick  let me try to clarify we have 4  from dc2 to dc5 . there are a mixture of 2013 and 2016


 When dc02 goes down anyone who has not logged into the domain yet will not log in 

Anywho has login prior still will able to login since its cache


We also have thin clients that no longer can not login into our domain if dc02 goes down again no other dc has this effect


The Thin client is the best way for me to test this since even after login it does not cache login


The DC02 has a static IP with static DNS all dc do.

The DNS of DC2 points to dc04 and dc05


every other dc dns point to other dc none of them point to dc02


The dchp configuration has nothing point to or referring to dc02

I enclosed all you want in a zip file




Please do not zip the files.



sorry I did not see the link we upload to that instead
k, save to onedrive how to I send the share to you (its all unzip)

Post a link here



Nothing there. 


@Dave Patrick 


yum yes there is






@Dave Patrick I do not know what tell you I see them can I just attached here unziped


Sounds good, you can start a case here with product support.




@Dave Patrick  also we do not have tech support I have to get approval from my manager is there any way to solve this issue with the logs I gave you?

- On DC03 I'd disable the unused adapter
- On dc02 connection properties has a DNS error should be

- you didn't post the problem member so I can't tell what issue there might be there.

- Looks like there may be replication problems so I'd check the event logs on each domain controller and correct the issues found.
