@RajanieshKaushikk-3057
Here is a update of the case. I review the information you provided above. It seems that the metadata have been corrupted. I found that the downloaded updates are all .exe files in the software distribution log in your environment:
94700-4.png

However, the updates files are all .cab in my environment:
94735-7.png

The .cab files are Binary update files which are used to be installed on the clients.


Please help to confirm the followings first:
1. Make sure that the Firewall is running on the WSUS server first.
2. Change all the Approved updates to Not Approved Please refer to the below picture:
Filter out all the approved updates:

Change the Approved updates to Not Approved

3. Please consider running the wsusutil.exe reset command on the WSUS server to reset the metadata.
Open the CMD as an administrator and then navigate to wsusutil.exe tool. Last post the wsusutil.exe reset command to reset the metadata.
4. Please consider approving the needed updates again.

Hope the above will be helpful.

Regards,
Rita

Hello Rajaniesh,

Thanks for your posting on Q&A.

I found a related link and it seems that the issue is more related with Firewall. Please try to start the Windows Firewall service if you haven't before on the WSUS server.

Note that the link is not from Microsoft, just for your reference.

Hope the above will be helpful. Have a nice day.

Rita

I disabled the firewall to check because when it was enabled it was not working

Hello Rajaniesh,

Thanks for your feedback.

What is the OS platform of your WSUS Server? Is a standalone WSUS Server or a downstream WSUS server?

Regards,
Rita

Is it a autonomous mode WSUS server or a replica mode WSUS server?

Run the WSUS Server Configuration Wizard again on the downstream WSUS server and sync from the upstream WSUS Server to see whether this issue will be resolved or not.

You approved the updates on the downstream WSUS server and the error occurred. Right?

Running the WSUS Server Configuration Wizard isn't helpful. Right?

Have you tried to approve the other updates on the download WSUS server and confirm whether this issue appear or not?

config wizard did not resolve it. Approving the updates on downstream server did not resolved it and approving other updates also did not resolved it. Actually it shows that some updates are downloaded 100% abd some are 65% and 25% but if you ho to downloaded location it shows zero bytes means nothing is downloaded.

Please help to confirm the following steps first:
1. Store update files locally on this server option

2. Please help to confirm the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Update Services\Server\Setup registry value.

Hello Rajaniesh,

Is there a proxy in your environment? Did the proxy work well ?

The Event ID 364 There are no more endpoints available from EndPoint Mapper indicate that the WSUS server could not get the update files from Microsoft Update. It is recommended to review the software distribution log and confirm the URL which the updates get from actually. Then we could try to connect to the link in IE browser.

In addition, please consider sharing the KB number you have approved. I would like to test it in my lab environment.

Thanks for your understanding and cooperation.

No proxy in our environment. I already connected to the URL and it downloads some files. I have tried installing it two times but no clue!! No KB number is getting downloaded for some of them it shows 100% or 75% or 25% but in the folder it does not show any content(shows zero mb). Also now it shows error 10032 event code.

no more endpoints available from the endpoint mapper


this occurs when some process that uses dynamics ports is called repeatedly and never completes. It consumes all the dynamic ports

netstat -aon
should show this. As a work around try rebooting.
