Messaging router forwards instant messages to the
Instant Messaging home servers on your
network. When an Instant Messaging router receives an instant
message addressed to a particular user, it locates the user and
forwards the message to the user's home server.
Before you create an Instant Messaging router, determine the
Instant Messaging domain this Instant Messaging router will
service, for example, "im.microsoft.com."
On the Start menu, point to
Programs, point to Microsoft Exchange, and then click
Navigate to the
Protocols folder for the physical server on which you want
to create the Instant Messaging router.
Right-click Instant Messaging (RVP), click New,
and then click Instant Messaging Virtual Server. This starts
New Instant Messaging Virtual Server Wizard.
As you step through the wizard, provide the following
Display Name. The name displayed in
IIS Virtual Server. The name of the IIS
virtual server where you want to host the router. Use the "Default
Web Site" created by IIS, which is the default choice in the wizard
and is appropriate for most situations.
Note If you want to install
multiple virtual servers on a single machine (a highly uncommon
situation for routers), you need to first create an IIS virtual server
with the Instant Messaging domain name you determined before, and
then select this as the IIS virtual server to use as the Instant
Messaging virtual server.
DNS domain name. Use the Instant Messaging domain that
you identified before starting this procedure. Type in the Instant
Messaging domain name if it is different from the domain name
displayed in the wizard.
Allow this server to host user accounts. Be sure this
check box is NOT selected, and then click Next.
Click Finish to complete the wizard.
The Instant Messaging domain name determined previously must be
DNS-resolvable throughout your installation, wherever your Instant
Messaging clients are used. Create the necessary Domain Name
Service (DNS) resource records for the Instant Messaging
router. If you will have more than one Instant Messaging router,
each router must have a host address (A) record.
Note For a group of Instant
Messaging routers that have the same Instant Messaging domain name
(the typical situation for large installations), use DNS round
robining to translate the same domain name to the different IP
addresses of the routers.
If you want Instant Messaging Internet
connectivity between your installation and other Exchange Instant
Messaging installations, make sure your Instant Messaging domain
name is also DNS-resolvable externally, that is, from outside your
organization. Depending on the type of firewall security desired,
the external DNS A-records you create can point either directly to
your Instant Messaging routers, or to HTTP reverse proxies that
proxy inbound Instant Messaging traffic to the routers.
