Hello, I am new to Sharepoint to CA configuration.
I have tried to create an web application, and half way during the creation, I got an error.
Now I want to delete the Web Application and I got this error:Â Object reference not set to an instance of an object.
I tried using powershell to remove the web application also got error.
I have checked the Content DB is empty, IIS doesn’t show this site, virtual directory doesn’t exist.
How do it solve this?

Vin

Thats great Vin and thanks for posting solution for others
Hi Ajeet,
I have found the solution for this, simply point the web application to another web application IIS using this function:
Function Set-WebApplicataionPool($WebAppURL,$ApplicationPoolName){
$apppool = [Microsoft.SharePoint.Administration.SPWebService]::ContentService.ApplicationPools | where {$_.Name -eq $ApplicationPoolName}
if ($apppool -eq $null){
write-host -foreground red “The Application Pool $ApplicationPoolName does not exist!”
return 1
}
$webapp = get-spwebapplication -Identity $WebAppUrl
if ($webapp -eq $null){
write-host -foreground red “The Web Application $WebAppUrl does not exist!”
return 1
}
$webapp.Applicationpool = $apppool
$webApp.Update()
$webApp.ProvisionGlobally()
write-host -foreground green “$WebappURL Application Pool has been changed to $ApplicationPoolName”
return 0
}
Set-WebApplicataionPool -WebAppURL “http://sitename” -ApplicationPoolName “SharePoint – SiteName”
source from:Â Cannot Create, Extend, or Delete a Web Application in Central Administration
Hope this help to someone!!

Vin

Hi Vin,
To get exact issue do following:
1- Click on technical Details link and get the correlation id.
2- use the PowerShell cmdLet to retrieve the information from log (Though you can check it from Logs also but is very tedious task)
you can get the PowerShell cmdLet from here.
3- Then check the issue else post the same here so we can provide some help to you.
