Issue the following command:
PolicyAgent-base\iis\bin\IISadmin.vbs -a REMOVEFILTER -f AccessManagerAgent
where PolicyAgent-base represents the directory in which the web agent was originally installed. The following is an example of how the command would appear with the PolicyAgent-base place holder replaced with the default installation directory:
c:\Sun\Access_Manager\Agents\2.2\iis\bin\IISadmin.vbs -a REMOVEFILTER -f AccessManagerAgent
