If you are like me and did a single box farm installation of SharePoint 2010, you might get to an error whenever you have configured your search.

I configured the search to crawl my local SharePoint Sites and when it did a full crawl it gave me the following error:

Access is denied. Verify that either the Default Content Access Account has access to this repository, or add a crawl rule to crawl this repository. If the repository being crawled is a SharePoint repository, verify that the account you are using has “Full Read” permissions on the SharePoint Web Application being crawled.

This error is caused by the local loopback check.

You can disable the loopback check by setting the DisableLoopbackCheckregistry key. To set the DisableLoopbackCheck registry key, follow these steps

1. Click Start, click Run, type regedit, and then click OK.
2. In Registry Editor, locate and then click the following registry key:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

3. Right-click Lsa, point to New, and then click DWORD Value.
4. Type DisableLoopbackCheck, and then press ENTER.
5. Right-click DisableLoopbackCheck, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Quit Registry Editor, and then restart your computer.

You can now also browse your site on your local server
