The page cannot be found HTTP 404 - file not found on the Search Administration site after installing Infrastructure Update

After installing the Infrastructure Update (KBs 951695 and 951297) and successfully complete the upgrade, you note that, within the SSP Administration page, you do not see the “Search Administration” link.  Instead, you click on the “Search Settings” link.  Within that page, that has the correct link to Search Administration.  However, you get a HTTP 404 error.

This appears to be a result of the proper S2 (Search Server 2008) features not being installed properly during the upgrade.  As you may be aware, the IU adds numerous search enhancements, including features from S2.  So, we have to force the features to deploy.

Navigate to C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN.

Issue the following commands:

1. stsadm -o activatefeature -filename S2BaseSiteStapling\Feature.xml –url https://server/ssp/admin –force

2. stsadm -o activatefeature -filename S2SearchAdmin\Feature.xml -url
https://server/ssp/admin –force

3. stsadm -o activatefeature -filename S2SiteAdmin\Feature.xml -url
