Authentication to Web Application
We have a development MOSS 2007 environment (we are currently planning our production deployment). With the initial install, I had the web application named the same as the server name, but I added a web application with the same naming structure that we are going to have in production ....http://dev.intranet.xxx.xxx. I moved several sites over to the new web application, but for some reason, I can authenticate to these sites without any problem when I am not on the server, but if I try to reach them from a browser actually on the server, it denies authentication. This is causing search crawls to fail due to authentication. I've done web searches to try to find similar problems, but nothing I've tried works. Any advice would be helpful. Thank you.

You have to disable authentication loopback check. This is the old issue. 1. Click Start, click Run, type regedit, and then click OK. 2. Locate and then click the following registry subkey: 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. Exit Registry Editor. 8. Restart the computer. Oleg
