Hi,

Is there any customization done on this site collection, if yes revert it back and try to access the site again,

Check the DB for this particular not working site collection is under Read-Only mode in SQL.

Identify your web apps' app pool account using inetmgr and Login to central site administration ->
Go to Application management > Policy for web application ->Choose the web application where the inaccessible site collection exists -> Add a full control policy for the app pool account. 

Hope this helps :)

HI Reema,

thanks for your help.

well i did everything as you suggested but none of them helped me yet so trying to backup/restore whole db and mounting back to SharePoint site collection which may help us. well, its production issue but SQL guys have prod backup db ready because they take backup everyday so it makes our life easy.

Thanks,

Reema,

well we tested both way but still not working and getting same error.

Let me know if you can find any other way to resolve issue.

Thanks,

Deepak

Cause of issue :A web portal application pool account is one of our service account which was not part of our limited people picker for this site collection.

Solution:

Finally issue has been fixed by allowing Service Accounts of other OU of domain to access site by changing people picker limit as following by powershell,

PowerShell:

$site = Get-SPSite https://site

$site.UserAccountDirectoryPath = ;

Thanks,

Deepak Patel
