In-Depth Information
The following command will add a RADIUS accounting server named server2.
mycompany.com to the local RRAS server (note that in this example, we've omitted the
optional name = before the server name):
> netsh ras aaaa add acctserver server2.mycompany.com
How It Works
The Windows Server 2003 RAS can use Windows authentication, such as Active Directory or a
Windows NT domain, to authenticate remote users, or it can forward authentication requests
to a RADIUS server. You can also choose to log information about successful and failed
connection attempts using the Windows accounting provider (using local log files) or by
forwarding accounting messages to a RADIUS server. In a large, heterogeneous environment,
it can be useful to configure some or all of your Windows RRAS servers to use RADIUS for one
or both of these functions. You have a great deal of flexibility in this matter, however, as you
can configure different RRAS servers or groups of servers to use different authentication and
accounting providers.
When configuring a RADIUS authentication and accounting provider, you can customize
a number of configuration details about the servers you're using.

6-17. Migrating IAS Configuration to Another Server
Problem
You want to copy the configuration information from one IAS server to another. This is often
useful in large server farms containing many IAS servers that need to be configured identically,
since it allows a standard configuration to be deployed quickly and with reduced risk of error.
Solution
Using a Command-Line Interface
The following command exports the current server's IAS configuration to a file called c:\ias.txt :
> netsh aaaa show config > c:\ias.txt
The following command imports the settings contained in c:\ias.txt into the current
server's IAS configuration:
> netsh exec c:\ias.txt
