I have local domain www.abc.com and set in DNS server and related IIS server. my clients can browse intranet web site but users that have firewall client couldn't see the web site when ISA server is not connected to internet (although I defined the domain in LDT). when ISA connected to internet firewall clients can see local web site and internet sites too. Now I need to know how my firewall clients can see my intranet web site when ISA is not connected to internet? Thanks in advance.
