Sharepoint - Access denied error in crawl log

This Solution worked for me:

You need to disable the LoopBackRequest in registry. To do this, just follow my instructions:

1. Go to command window and type regedit.exe

2. Once opened the registry editor, just navigate to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa"

3. Right click on "Lsa" and create a new 32bit DWORD value

4. Rename it as "DisableLoopbackCheck" (Note: you cannot rename it actually. so, once created the DWORD value, directly paste/type as "DisableLoopbackCheck".

5. Then again modify the value of "DisableLoopbackCheck" as "1"

6. Close the registry editor.
7. Now start to crawl the content.
