We have added a Windows Server 2019 to our network to host websites. We have tooling that uses Microsoft.Web.Administration to manage IIS however it cannot connect to the new server. I have searched a lot and found people with similar problems but have not yet found any solution that works. Any help would be greatly appreciated.

We get the following error everytime our tools try to connect to the server:

    @Scott E

    It could be various reasons for this error, like permissions or misconfiguration of application pool, etc. Here, we have mentioned some settings that may help to fix your issue.

    1. Ensure that your application pool identity has the proper permission for the website root folder. Also, be sure about your application pool identity user(IIS Apppool\<app pool name>) before applying for permission. If the issue doesn't fix, you can go for the other options.
    2. You may be running on a windows server with 64 bit OS. try to enable 32-bit applications for the Application Pool. Go to Websites >Select the application pool your 32-bit application will run under > Click Advanced setting > Set Enable 32-bit Applications to True.
    3. Provide read/write permission to the website application pool identity to the C:\Windows\Temp folder.

    Besides, if you need to remote administration the IIS, please ensure you have set the IIS management service correctly: delegating-iis-administration-to-domain-users-non-administrators.

    This make me think the issue has to be with a security change

    Do you see any logon failures in the security eventlog on the destination server? And at the same time, do you see a successful logon for the app pool identity account when you try to connect?

    Have you reviewed the dcomcnfg access permissions?

    If you run the code that you posted interactively with an account that has admin access on the target server, is it able to connect?
