Disable Loop back if getting the "access denied, verify either the default content access" error

Disable Loopback

Issue: File share Crawl on file:\\localhost\document has ab error with "access is denied, verify either the default content access ...."

Solution: Set DisableLoopbackCheck to "1" in Registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

Update: Disable loopback is also needed for creating apps in sharepoint hosted, when tried to register its own domain.

When the sharepoint web service is called, you may get the access is denied error.

Also after this is done, need to restart the server for it to be effective.
