Hi Arthus, You can make this work for caching only mode. The problem will be that you'll need to replicate the user names and passwords for all hosts on the local SAM of the proxy, since its not a member of the domain.

[mailto:alim@xxxxxxxxx] Sent: Monday, September 08, 2003 8:23 PM To: [ISAserver.org Discussion List] Subject: [isalist] ISA within ISA http://www.ISAserver.org I've created a workgroup separated from our domain for security reasons. The workstations within the workgroup use 1 server that contains the database, I want that server to act as proxy server and dhcp server at the same time. The server has 2 NICS one connected to the rest of the workstations within the workgroup and the other one to our domain, so in effect the server is not using any public IP and it is the only connection to our domain. Is this setup possible in ISA? If yes, how will I going to configure it? In effect I'll be using a proxy server within a proxy server. The server uses win2k and SP4. Also, allow me to ask you if dhcp server can be used in the said setup? I'm having problem configuring the DHCP server. I couldn't able to start the DHCP server service. Thank you and more power! ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
