You can prevent applications from gaining network access based on their name. "Don't let anybody named Jeff into this cool club." Similarly, if you use Systems Management Server, you can register and then block these programs, including by date/time and user. -----Original Message----- From: Jeff Herr [mailto:Jeff.Herr@xxxxxxxxxxxxxxx] Sent: Monday, August 27, 2001 3:02 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Yahoo http://www.ISAserver.org what did you mean by .... 1.Block the YPAGER.EXE and the YUPDATER.EXE executables in the wspclnt.ini file explain Jeff Herr IT Manager http://www.teleplan-ca.com 8875 Washington Blvd, Suite 'B' Roseville, California 95678 916.677.4538 -----Original Message----- From: Thomas W.

Remember to create a Destination Set that includes this site so that you can create the Rule. 3.The SOCKS4 Application Filter must be disabled. Users can reconfigure the Yahoo IM'er as SOCKS 4 or SOCKS 5 clients. ISA Server does not support SOCKS 5, but they can get out using SOCKS 4. Since few legitimate Windows applications use SOCKS, you can safely disable the filter.
