ISA Server Restrictions?

I have recently taken over at a school as Network Admin. I noticed that many of the PCs take a very long time to startup. They display the message "Installing Managed Software Microsoft Firewall Client". Is this ISA Server or something else? I really do not see the need for an ISA Server in this enviroment. Can anyone give me some recommendations on getting rid of this huge (5-7 min) delay, and why would I need an ISA Server in a school enviroment. This is not Fort Knox. Thanks.

PS: This is not a corrupt build issue. It even happens on brand new builds that are fast until they join the Domain and get under the influence of it. I am thinking ISA, but I have little experience with it.

The Microsoft Firewall Client can be used in conjunction with ISA Server.  The client is an optional component and you can use ISA without installing the Firewall Client.  

The installation of the client is probably being initiated by a group policy in Active Directory.
It is the ISA server firewall client.  It's in a group policy (possibly the default domain policy) under the Software Installations.  It's called MS_FWC.msi

The ISA server is a proxy and firewall server, so you need to really make sure if you want to remove it that you have other firewalls and replacements in place.  You need to get into the ISA server and look at the firewall settings/rules and see what it is doing in order to make that kind of decision.
