You can see that the failure was while activating the feature called DocumentSet. In this process it attempts to check if the feature is a SafeControl – for which it would need to look at the web.config file of the web application in IIS. This is when You found that the affected web applications had no files in the IIS virtual directory on the server. They were missing which was causing the unexpected error at site collection creation. How to fix this? You provisioned these web applications to bring back these files: Add-pssnapin microsoft.sharepoint.powershell $contentservice = [Microsoft.sharepoint.Administration.spwebservice]::contentservice $webapp = $contentservice.webapplications | where { $_.name -match YOUR_WEB_APP_NAME } $webapp.provision() After this You were able to create site collections on the re-provisioned web application. You test created that web application but that was timing out. So You did this on the central admin application pool in IIS: IIS Manager > App Pool > Central Admin App Pool > Shut Down Limit > Changed this from 90 seconds to 600 Seconds After this You were able to create web applications from central admin site successfully. You also noticed that web application creation was taking unusually long to complete. One tip to improve the performance would be to disable Receive Side Scaling and TCP Offloads on the SharePoint and SQL Servers.
