Log in to the Microsoft IIS 6.0 Server as an administrator.
In the Microsoft Windows Start menu, choose run.
Type the following: inetmgr.
Expand the local computer.
Expand the Web Sites folder.
Right-click Default Web Site.
An options list appears.
In the options list, click Properties.
Click the ISAPI Filters tab.
Click the amiis6auth filter.
After removing the filter manually, as described in this task, if you want to reactivate it or if you want to unconfigure the agent by issuing the IS6AuthAdmin -unconfig command, you must first add the filter back manually (see Microsoft Office SharePoint and Outlook Web Access: To Reactivate the Access Manager Policy Filter) with the same filter name, for example amiis6auth. Otherwise, an error will be issued.
Restart the Microsoft IIS 6.0 Server.
A method for restarting this server is to enter iisreset in a command window.
