Cause: There can be many reasons why Firewall
Client is not properly installed. The setup program in the Firewall
Client software creates a log file on the client computer each time
client software is installed. The log file contains information
about the setup, including information about which client
applications were installed and which services were started.
Solution: You can use the log file to
troubleshoot problems with setup. The log file name is
Firewallc.log, and it is located in the Firewall Client software
installation directory. ISA Server overwrites this log file each
time you install the Firewall Client software.
