By default, Internet Information Services 6.0 (IIS 6.0) is configured to serve only static content. The Web Service Extension node in IIS Manager provides the interface you can use to allow or not allow existing ISAPI extensions such as Active Server Pages (ASP) or other extensions that the Web administrator may add.

After a Web service extension has been added, the name cannot be changed through the user interface. The only way to rename a Web service extension is to edit the metabase (Metabase.xml). You can also delete and re-create the Web service extension through IIS Manager.

Warning If you edit the metabase incorrectly, you can cause serious problems that may require you to reinstall any product that uses the metabase. Microsoft cannot guarantee that problems that result if you incorrectly edit the metabase can be solved. Edit the metabase at your own risk.

Note Always back up the metabase before you edit it.

To rename a Web service extension after it has been added:

1.	To directly edit the metabase, open IIS Manager, and then right-click the server name node.
2.	Click Properties, and then click to select the Enable Direct Metabase Edit check box.
3.	Close IIS Manager, and then locate C:\Windows\System32\Inetsrv\Metabase.xml.
4.	Right-click Metabase.xml, and then click Edit. The file opens in Notepad.
5.	Find the WebSvcExtRestrictionList property and edit the extension name that you want to change.
6.	Save and close Metabase.xml.
7.	Open IIS Manager, and then right-click the server name node.
8.	Click Properties, and then click to clear the Enable Direct Metabase Edit check box.
