For TMCM agents using Trend Micro Management Infrastructure (TMI), when you click Administration > Control Manager on the OfficeScan web console, a username and password field appears under Web server authentication.
You do not need to enter any TMCM account when registering the OfficeScan server to the TMCM server. The web server authentication fields are used by the Internet Information Services (IIS) Web server, and not by the TMCM server itself. You only need to enter a username and password if the IIS Web server of TMCM requires authentication.
