You are configuring an ISA Server installation for Firewall and Web caching service in each of two company branch offices. You need to assess requirements and make recommendations about how to configure the client computers. In addition to the 20 employees at each branch office, there are 10 field workers who spend time at both offices and who plug their portable computers into any available Ethernet port when they arrive at either office. The office desktop computers are more or less permanently positioned, and you do not anticipate that you will need to set specific access rules configured for any user accounts. To maximize efficiency for installation and maintenance, which (if any) computers do you recommend be configured as SecureNAT clients, and which (if any) as firewall clients? What is the difference between the Mspclnt.ini file and the Wspcfg.ini file on Firewall Client computers? When automatic discovery is configured, what are the steps it takes to fulfill a client request? Does configuring dial-up entries in ISA Server allow you to share a secure Internet dial-up connection among Web Proxy clients? Having recently switched from a dedicated connection to a dial-up connection to the Internet, you disabled your external network adapter and configured a dial-up entry for your existing dial-up connection. However, when your ISA Server dials up to your ISP through this dial-up connection, none of your clients can connect to the Internet any longer. What is the first step you should take to troubleshoot the problem?
