Hi,
see Tamino Online Documentaion chapter Installing Tamino / subchapter Configuring Tamino / section Configuration of WebServers. (for version 2.3)
If IIS is running at the time Tamino is being installed, Tamino configures the webserver for you.
If this for some reason has not happend, stick to the description at above location.
With IIS it is essential to install the ISAPI filter with the root server, not with one of the instances.
Best regards, Andreas
