Hello Wesley Dew

On investigation found out that Shared configuration was not configured correctly in IIS. The credentials were updated. Post updating, IIS started working fine. Below is the sample example of place where credentials were updated. (David So's Blog - IIS and Azure Files)

Make sure that the file share is set up correctly and that your IIS servers have proper access to the shared configuration file located on the Azure File share.

You must complete the following steps in order:

  1. Install IIS on your server, which will be referred to as the Web Server throughout this article.
  2. Ensure access to a second server, which will be referred to as the File Server throughout this article. The File Server will house the share for configuration and basic content, which can be accessed by using UNC.
  3. Each step of this article assumes that the previous step was completed. Perform all steps in order.
  4. For some steps, there is an equivalent step that can be done by using the UI. Perform only one type of step, unless specified otherwise.

I hope this was helpful!
