We are running ISA on 2 Windows 2003 servers clustered with rainwall. For some reason about a week ago all of the clients running the isa script &nbsp; http://isa.domain.com/array.dll?Get.Routing.Script&nbsp;in there connection settings cannot connect to certain sites. If we remove the check for that option and just select to use proxy server and manually input the shared ip or isa.domain.com for the cluster, everything works fine. What can be causing this?<br />

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
