Enabling RRAS
RRAS automatically installed during W2K
server installation
 But RRAS is disabled by default
 You must enable RRAS and configure it to:

 Setup
a network router
 Setup a RAS server
 Setup a Virtual Private Network (VPN) server

Click Start/Programs/Administrative Tools
Click Routing and Remote Access
In the console tree, select the server on which you want
to activate RRAS
Click Action/Configure and Enable Routing and Remote
Access to open the RRAS setup wizard
Click Next to open the Common Configurations screen
Click Manually Configured Server to enable the server
with default settings
Click Next, then Finish
When asked “Do you want to start the RRAS?”, click
Yes.

Configuring RRAS
When RRAS is manually enabled, the
default settings apply.
 You can configure RRAS according to your
requirements at a later date.
 To configure RRAS, you use the Properties
dialog box (Right-click server, click
Properties)

Configuring RRAS
Note: Tabs depend on
protocols installed on
your server

Logging
Used to specify whether server will be configured
as a router for LAN only, as a router for a LAN
and demand-dial routing, as a RAS, or both a
router and a RAS
Used to choose one of two types of authentication
providers to validate remote access clients
Used to specify settings for the IP protocols (e.g.
method for distributing IP addresses to remote
clients.
Used to configure Point-to-Point Protocol to
specify whether a remote client can establish
multilink connections
Used to manage and monitor a RRAS server by
selecting the type of event to record.

Open Routing and Remote Access console if necessary
Right-click RRAS server and click Properties
Notice the default selections in the General tab.
Click the IP tab. Make sure that the Enable IP routing and the
Allow IP-based remote access and demand-dial connections
check boxes are selected. Note: if you allow IP routing, dialup clients can access the entire LAN. If you only want to allow
dial-up clients to access resources on the RRAS server, clear
this check box.
Click the Security tab. Windows Authentication is the default
provider and Windows accounting is the accounting provider
by default.
Click the Event Logging tab. You should select the Log the
maximum amount of information option button and the Enable
Point-to-Point (PPP) logging check box if you want to
troubleshoot connection problems.

Click OK to close the Properties dialog box.
Monitoring RRAS

In the server Status node in the Routing and
Remote Access console, you can verify:
 the
state of the server (started, Stopped, Paused)
 The type of server
 The number of ports in use
 The Up time (length of time server has been running
since RRAS server was last started).

The log files that contains the monitoring data
are stored by default in the
%systemroot%\systems32\LogFiles folder,

Open Routing and Remote Access console if necessary
Double-click the RRAS server to expand the node. Select
Remote Access Logging.
Right-click Local File in the Details pane and click Properties
On the Settings tab of the Local File Properties dialog box,
select Log Accounting Requests to capture accounting
requests and responses
Select Log Authentication requests to capture authentication
requests such as access-accept packets, and access-reject
packets.
Click the Local File tab to specify a time period for the log file.
Click the Monthy option button in the New Log Time Period
section
Click OK to close the Local File Properties dialog box.
Note: Can use the Net Shell (Netsh) command-line utility to manage and troubleshoot RRAS.

Creating a Remote Access Policy

Remote Access Policies are used to:
 Control
what connections attempts will be rejected
 Determine which users can access the network and to
prevent unauthorized access.
 Determine connection time, etc.

Three components in Remote Access Policy:
 Conditions,

Permissions, and Profile.
Remote Access Policies are usually stored
locally on the RRAS server. They are not stored
in Active Directory.
