Updating permissions settting for file the file permissions setting were supposed to be set to 'D:P

I got the below error while performing SQL Server 2008 R2 installation with NT Authority\Network Service account









Workaround :


1. Run cacls and icacls and add network service to all your mount points
2. Make sure you don't see any access denied messages when you run step 1
3. If you see any access denied message then explicitly specify full permissions to Network Service from the mount point / folder security
