  • IIS Web Farm configuration change problem

    Mar 24, 2020 06:50 AM|cagdass|LINK

    Hello,

    We have 2 IIS Servers running on Server 2016 with shared configuration. I will mention "Server A" and "Server B" after this. We are using DFS for sync to the configurations. IIS configurations are locating some folder under C: drive. We are using this topology for many years. Nowadays we have problem. Whenever I change any configuration like site binding or new sub application on Server A, DFS will working fine, I can see the change inside the applicationHost.config file on Server B, but IIS service on Server B does not realize the change until i restart the app. Same thing exist both servers. Any change on Server B does not reflect Server A although I see the change inside the applicationHost.config file. applicationHost.config file is just 250KB. This situation started after I did up to date the servers. I tried uninstall the updates but some updates cannot be uninstalled. I tested this situation on Server 2016 and Server 2019 on my test environment. When i build topology without any windows update, they are working fine. But after windows update, problem begins. On 2016 IIS servers, there are 3 windows update packages. KB4537764, KB4520724 and KB4049065. As i dig, there are no reported bugs about this situation. 

    So, do you have any solution or fix related to this problem?

    We are using DFS for sync to the configurations.

    Microsoft only supports its own "shared configuration" https://docs.microsoft.com/en-us/iis/manage/managing-your-configuration-settings/shared-configuration_264

    We are using this topology for many years.

    No surprise. But if an option is not from Microsoft's documentation, it can break anytime.
