DNS - Domain Name Services; the services residing on a computer that are able to answer a name resolution query.

How they answer that query depends isa server 2008 configuration many settings for that server.

FQDN — Fully Qualified Domain Name; this is a computer name that indicates its logical association by virtue of the domain structure associated with the name.

Cache — This is the least capable mode, since only the Web Proxy and optionally, the caching services are installed and running. This is also isa server 2008 configuration only mode that cannot support the H. Server publishing — with this feature, clients from the public Internet are directed to the ISA Server instead of to the web server.

Moreover, the ISA Server may act as the proxy for inbound and outbound traffic between the public Internet clients and the internal web server.

With Cache Configuration tab the user is guided through Web service configuring. In addition to a variety isa server 2008 configuration settings, the possibility exists to set up the size of the cache memory per hard disk and configure the schedule of caching tasks TTL utility.

How to configure an ISA Server computer for a very large number of authentication requests

Forward Web Caching Server — this is the most popular use of the Web caching server. Its function is as follows: The Isa server 2008 configuration Server approves the request and checks if the object already exists in the local cache.

If the content does not already exist in the cache, the ISA Server contacts the Web server to fetch the requested object on behalf of the user ; isa server 2008 configuration.

To do this, install the update that is described in the following Knowledge Base article on the servers: This helps the server perform better when isa server 2008 configuration traffic is high.

To load balance the Web requests and authentication and to increase performance, you can also use more ISA Server computers in an array. You should set the value on the resource server and all intermediate DCs handling the NTLM authentication request on the path to the user domain.
