Ident simulation service
Microsoft Internet Security and Acceleration (ISA) Server includes an Ident server (also called Identd) that responds to Ident queries from the Internet.
Some Internet servers (typically File Transfer Protocol (FTP), Simple Mail Transport Protocol (SMTP), and Internet relay chat (IRC) servers require identification from a client before providing services to the client. To do this, the server sends an identification protocol query to the client. When the client is located behind ISA Server (or any other proxy server), the Ident request is dropped and never reaches the client.
Running the Identd Simulation service that is included with ISA Server allows the ISA Server computer to respond to the Ident query on behalf of the client. ISA Server always responds to the Ident query with a random user identification string.
Perform the following steps to install and configure the Identd Simulation service:
1. | On the computer that is running ISA Server, create a folder named \Identd. | ||||||||
2. | Copy Identd.exe from the ISA_Server_CD-ROM\ISA\Identd\Platform\ folder to the folder you created in step 1. | ||||||||
3. | At a command prompt, in the Identd folder on the ISA Server computer, type identd -install. | ||||||||
4. | At a command prompt, type net start identd. | ||||||||
5. | Create an IP packet filter with the following parameters:
