Hi All: I found at http://www.isaserver.org/faq/setup/ : General ISA Server setup questions, this entry: How do I perform a silent installation of the Firewall client for Win2k and Windows NT client computers? Date - Jul 04, 2002 Author - Thomas Shinder Try this: \\%isaserver%\MSPCLNT\SETUP.EXE /v"/qb+/r:n" Many thanks to Lemonwater925 for this tip! Some body could explain the meaning of each flag in the command ?qb+/r:n" ? I tried it and it works, but it configures the IExplorer to automatic detect settings, and I would like that it checks the proxy server box and sets the proxy server name instead. Thanks in advance.
