Hi, thanks for your time. Web Proxy Clients appears as Firewall Clients!!!??? 1. I have ISA Server (SP1) installed on a w2k. 2. The objects of the ISA are in the Active Directory Schema. 3. There are Two NICs on the ISA Server PC. When I configure a rule for FTP Access "Applied to any request o to a group of IPs" everything is ok, but when I Applie this rule to a especific group of users there is no access and the Clients appears to be Firewall clients. Some days ago I installed a computer with W95, IE 3.01 and while nobody got access to FTP sites aoutside my network that PC got it, I updated IE to version 4.0 and everything OK, but que updated to IE 5.0, the situation was the same for this PC too. When I install firewall client software on workstatios no more problen with FTP access, but I think taht is not the solution. This situation is diferent with HTTP, I separate the rules (one for FTP & one for HTTP) and I am applying the rule to the especific group of users without problems. Does anyone know what is going on? Thanks for your time, again. Saludos, Lesky Alfonso M.
