http://www.ISAserver.org Checked protocol rules -> same as before with no apparently problem. ISA server is not on a domain controller it is an independent machine. I tried even with a allow all protocol to any request rule and nothing. All computers are on the same subnet. Checked the LAT -> OK. DHCP has plenty addresses to give. Ping to outside allowed. Could it be a problem the fact that we have a supernet DHCP 192.168.1.x - 192.168.3.x (shouldn't be - the ISA and most of the computers with problems were in 192.168.2.x) ------------------------------------------------------ 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 ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: NVuba@xxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
