Restore IIS website on WFE

If you accidentally deleted the IIS site in any front-end server or you want to repair WFE IIS. Please use the below steps

When you have multiserver environment, your web application provisioning can go wrong due to many reasons (app pool timeout etc.) and as a result you can get one WFE works while the other does not.

In my case, Deleted IIS folder in my on of WFE and want to restore and I don't want to recreate my web application from scratch. SharePoint provides Provision() and ProvisionGlobally() method.

We ran Provision() on the Deleted WFE and it fixed all our IIS sites (default and internet zone) in one go.

To do this just open power shell on the WFE:

?
$webApp = Get-SPWebApplication https://sharepointsiteURL.com/ 
$webApp.Provision()

$webApp = Get-SPWebApplication https://sharepointsiteURL.com/ 
$webApp.ProvisionGlobally()
If you want you can remove the IIS site completely in WFE IIS manager and Provision() will recreate the IIS site After executing the above commands in powershell

Assume that we have an input field named Feedback var feedbackField = $("input[title=Feedback]"); feedbackField.parent().parent().parent().hide();    But what if we want to hide the field for a particular SharePoint user group only. Let's say we have a user group named "Test Group" and we don't want to show the Feedback field to the users of this group.

In my case I created a folder named JS inside Shared Documents Document library and uploaded both files...
