Good Afternoon. Last night i changed from a Windows 2k Server with ISA server 2k to a Windows 2003 Server with ISA Server 2004 joined to the a Windows 2000 Domain. On the ISA 2k i had a VPN server configured through pptp and everything was working correctly. I've been reading tutorials but i get always stuck on the same place. When i try to "Enable VPN Client Access" an error message appears saying something like: "ISA Server unable to add this computer to the list of valid remote access servers in the active directory. etc," i tryed adding it on a domain controller like the help says: "Solution Log on to the computer with an account that has domain admin permissions. Launch the Active Directory Users and Computers MMC snap-in, and then double-click the domain name. Double-click the Users folder, and then double-click the RAS and IAS Servers security group. Select the Members tab, and add the server to this group. You will receive a message informing you whether registration is successful. " Could someone point me out to the right place?.. it's driving me nuts Thanks Miguel Silva
