Configure Alternate Access Mapping in Sharepoint 2010

Alternate access mapping is commonly used to rewrite SharePoint URLs to more meaningful ones. Some scenarios require configuring AAM since the URL of a web request received by IIS may not necessarily be the same as the one that the users entered in their browser

 

STEP # 01

Open the SharePoint Central Administration page. Click the Configure alternate access mappings link under Application Management.

STEP # 02

In the Alternate Access Mappings page, click on the Edit Public URLs link.

 

STEP # 03

On the Edit Public Zone URLs page, make sure that you select the correct web application that you want to configure for alternate access mappings. Under the Public URLs, section, enter the new URL that you want mapped to the existing web application.

 STEP # 04

In this step, we have to open the hosts file located at C:\Windows\System32\drivers\etc and add an entry for 127.0.0.1 and point it to the new URL. You might need to open the Notepad with 'Run As Administrator' permission in order to do this.

 

STEP # 05

Even though we told SharePoint to listen that doesn’t mean IIS is listening to the new URL. Open IIS Manager and select your site. On the far left panel you will see ‘Bindings…’. Once the binding window is open for your SharePoint site click ‘Add…’. Enter your new URL into the ‘Host name:’ text box. (don’t add the ‘http://’)

  

STEP # 06

A modification must be done to the server's registry to specify the host name. To specify the host names that are mapped to the loopback address and that can connect to Web sites on your computer, 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\MSV1_0

3)Right-click MSV1_0, point to New, and then click Multi-String Value.

Type BackConnectionHostNames, and then press ENTER.

4)Right-click BackConnectionHostNames, and then click Modify.

5)In the Value data box, type the host name or the host names for the sites that are on the local computer, and then click OK.

6)Exit Registry Editor, and then restart the computer.
