We are having a consulting company assist our company with the integration of ISA Server 2000 Enterprise for a pilot test site. I was wondering if anyone has a good guess estimate of the time needed to do the following: Install ISA Server 2000 Enterprise as a single Array The ISA Server will act as a Cache and Firewall 1 Web Server, 1 FTP Server, 1 Exchange Server (Actually a Filter Server gets hit before the Exchange Server) will be published with the best security. 5 Client Machines 2 running Firewall Client, 2 as SecureNAT and 1 as Proxy Client will connect. I am just trying to keep honest people honest and make sure we are not being overkilled with consulting hours. I do not have the install experience yet and really want to thank everyone in advance who can help. Joe.
