Thank you for replying, I followed your instructions by clearing the contents of the tranlog, temp, and wstemp folders, then restarted all nodes and used the syncNode command from the command prompt for node4, but node4 is still not visible in the console. Additionally, I encountered an error when attempting to stop the server.
On the network side, I was able to ping the deployment manager server from node4, but I am unable to ping the Active Directory (AD) server from node4.

Hariprasad,
As a first step, you can shutdown the node, and delete the contents, but not the folder, of tranlog, temp, and wstemp folders in the profile node folder. Then you can use the command line syncNode command to resync the node. This will force a full resync with the deployment manager, which may resolve your issue assuming it is some partial configuration state caused by your unexpected reboot.
That said, the error java.net.UnknownHostException: HOST_NAME_OF_AD indicates you may have a host level name resolution problem. I assume HOST_NAME_OF_AD is your redacted version of the hostname and not actually part of the error message. As a simple test, log on to the node4 host server and try to ping your HOST_NAME_OF_AD server. If it doesn't resolve then your host DNS configuration is probably corrupt or otherwise misconfigured.
Regards,
Jason

We're encountering issues with the node agent on `ctgNode4` within our WebSphere Application Server cluster. After the server automatically restarted (Unexpectedly), we manually restarted this specific node while other nodes on different servers remained operational. Since then, Active Directory (AD) authentication has been failing only on `UI4`, while AD users are able to log in successfully on other UIs.

Troubleshooting Steps Taken:
Restarted ctgNode4 node agent, but the issue persists.
Attempted synchronization through the WebSphere console, which fails due to the node being shown as inactive.
