Access Denied on the site collection after migrating form MOSS 2007 to SharePoint 2010.

We have recently migrated from the Moss 2007 to SharePoint Server 2010 and after migration we have several user complain about that they get access Denied error message on accessing parent site collection despite of they are having access on the site.

Error: Access Denied on the site collection level, though they have permissions. 

Background:

We user to activate a feature in the MOSS 2007 using stsadm -o activatefeature -name “Feature Name” -url  https://siteurl.net/sites/sites, after the site creation to have Branding enabled on it. 

After Migration, this feature is automatically activated on the web application level. Hence there is no need to activate it manually to apply standard branding on the newly created site. 

Troubleshooting:

-          Checked user permission on the group.

-          Added the user explicitly to the SharePoint group or individually.

-          Removed the user form the site collection and added again.

-          Added the user to site collection admin group. 

Note: We have seen Master page Gallery on the site collection level is using the unique permissions. Where as it has to be inherit from the site collection.

Resolution:

-          Added the NT Authority\Authenticated Users to the Master Page Gallery with Read permissions.

-          Change the permissions of the site to inherit form the site collection level.

-          Add the NT Authority\Authenticated Users to the style library with Read Permissions. 

Applied To:

SharePoint 2010. SharePoint Foundation 2010. SharePoint Server 2013.

The site collection could not be restored. If this problem persists, please make sure the content databases are available and have sufficient free space

Topology details:

-SharePoint Server 2010 with latest CU

-SQL Server 2008R2

-4 applications and 7 WFE’s

Problem Details:  Requirement comes up to replicate the production site collection to staging environment. We have taken the backup of the site by using PowerShell command without any issues.As soon as we started the restore command then it throws the following exception.

Error Message:

The site collection could not be restored. If this problem persists, please make sure the content databases are available and have sufficient free space.

Note:  One thing we need to understand that this is a very generic error message and does not have any correlation with the disk space available or not. If you have disk space available on the SQL Server as well as on the servers where SP is running then also you will face this error message. I think this is a BUG but not getting any documentation based on this to conclude the same. 

Troubleshooting done:

-Check the disk space on the SQL Server where LDF and MDF files are stored.

-Check the partition on the SQL SERVER in reference to data files

-Make sure the content database has enough space allocated.

-Make sure the databases does not have restrictive growth

-Make sure to check the disk space on the SP server where restore is running.  Approximately it should 2 times the DB size.

Resolution Applied:

-Go to “SQL Server Properties--Connections” and uncheck ‘Use query governor to prevent long-running queries’. Also, set “Remote query timeout” to 0.

-Stop and restart the "Windows SharePoint service Timer" 

-Restart IIS

I would be more than happy to help you as well as resolves your issues, thank you.
