Event Id 2436 Access denied in moss search

If you are getting the below error in event log in your SharePoint server 2007
"Access is denied. Check that the Default Content Access Account has access to this content, or add a crawl rule to crawl this content."

Then follow the below solution steps

Method 1: Disable the loopback check
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.
Method 2:- After I restarted the server I went to the Sharepoint Admin site and started a full crawl. Some seconds later I went to the crawl log and found a warning this time with the following entry:
Content for this URL is excluded by the server because a no-index attribute.
So  "Reset All Crawled Content" and tried the full crawl again.

Now it should work.
