Getting Error after Domain Controller Change

[Vatanjain11 (Vatan Jain)]

Hi Developers

Actually In active Directory Source we need to change our domain Controller.
So we are changing value of ‘Global Catalog Server’ in Forest Setting and ‘Server’ in Domain Setting.

I have test connection between Server and VA through below command:
Cmd

1. nslookup abcd.xyz.com
2. ipconfig /all

Powershell Command
$tcp = New-Object System.Net.Socket.TcpClient
$tcp.Connect(“abcd.xyz.com”, 636)
if($tcp.Connected) {“Port is Open!”} else {“Closed”}

everything looks good.

Certificate is in right directory on server as well on VA.

Either we are getting below Error while hit Test Connection:
We have detected an error from the managed system.

Error Received:

[ InvalidConfigurationException ] [ Possible suggestions ] Ensure that the DNS mapping is correct on your host. [ Error details ] Failed to connect to - dc=xyz,dc=com : java.lang.Exception: [ERROR 1] Failed to connect to server:ldap://abcd.xyz.com:636 - java.net.UnknownHostException: abcd.xyz.com

Can you please help to resolve issue.

Thanks
Vatan

Have you tried running netcat from the VA that is trying to connect? To ensure that the VA can talk to the new Domain Controller.
