Hi Anibal, When the clients do not have access to the internet, were you able to logon to the ISA server to check if you can access the Interent from the ISA Server? You should plan to install SP1 for ISA and get familiar with hfnetchk.exe utility at http://www.microsoft.com/technet/security/current.asp -----Original Message----- From: Aníbal Zaldívar C.
