we have one very strange issue which is causing because of changing our old DNS server IPs
I have changed old DNS ips to new DNS ips using local administrator account --- no issues found
logged-off from vcenter and trying to log-in back to vcenter using AD account --- we are having error message saying that invalid credentials
To me it looks AD integration in broken
This is totally unexpected behavior why would AD breaks with changing DNS IP address
vCSA version: 6.7 U2
can some one help me here?

Volga
I think you are missing something here
1) re-Join AD as IRIX201110141 mentioned in above thread
2) make sure you are rebooting vCSA
3) if you are rebooting and not working check for services or wait for 5 minutes if still not working reboot again
Note: sometime for vCSA it requires multiple re-boots

sorry to hear, I will try to help you here
I totally agree with you that this is unexpected outcome for changing DNS ips
can you able to log-in to vcenter with local accounts for example use local administrator account to log-in and let me know
if you can, try to do ssh and test [command: nslookup "vcenter-host-name" "new DNS ip"] based on this output I will give you next steps

any luck? let me know your feedback when you get a chance
sorry for not updating, lot of things going on at the same time
I can able to resolve vcenter from inside vCSA and also outside
we are investigating on it as a team but changing DNS ip is very simple task which should not break AD integration correct?
Thank you,
Volga.
well, technically changing DNS ips should not break existing AD integration and you should able to log-in to vcenter using AD account along with local account
I have not seen stating it in Known issues but don't worry
Thumb rule, revert to old snapshot [where no changes happened to vcenter] if you can live with using old DNS IPs
let me try something here from my side if I can replicate this issue
vcenter version is 6.7 U2 correct?
Unfortunately we did not have VM snapshot of good state, who thinks we will have this strange issue
yes correct we are on 6.7 U2 as vCSA, thanks for trying to replicating issue, let me know if you need any more information
Unjoin/Remove the Windows AD Integration and create a new one by using LDAP for Windows AD and not the first option from the list.

Hi Volga,
Yes, same in my case, it looks like something is not going good if you change DNS ips after initial build on vCSA 6.7 U2a
I tried removing and adding it back and it worked fine in my case [as also Joerg mentioned] but as you know I just build it in Lab to replicate your scenario, however hope it should work in your case as well
let me know if you need any steps or assistance here, me or someone else can help you
Regards,
Vkmr.
Thanks Joreg and Vkmr
I will give a try now and will let you know, one good thing is we are not using this vcenter for production
Thank you,
Volga
Below is my feedback,
I have tried rejoining the AD but it still same result, something is not correct or I am not doing it correct
while binding AD I got error and I tried again and this time it worked...
Thank you,
Volga.

Thanks everyone, issue got resolved now
I have done multiple reboots on vCSA and issue got resolved
Do any one know why we got this issue? is it unknown bug?
