1 versus 2 nics

We're migrating Outlook currently running on our workstations to Exchange. In
our server we have 1 nic and a router between the server and the internet. Is
it better to have 2 nics? As I understand it, you can't run Windows
Firewall/ICS with ony 1 nic.
Thanks in advance for your help.

Hello coopfab,

I can not really follow your description, Outlook runs normally on a workstation
and it is not recommended to run Outlook on an Eschange server.

A server should be not multihomed if possible, just because you have 2 NICs
dopesn't mean to use them on different networks, this can provide multiple
problems. And if you have router then use it for routing and let not the
server route traffic.

What are you trying to achive at the end with thsi setup?

Best regards

Sorry for my confusing question. Currently we're not using Microsoft
Exchange but would like to begin using it so key employees can access their
Outlook email, calender, and contacts with their smart phones. Exchange is
installed on the server but we haven't yet run CEICW. Right now the
workstations have the Windows Firewall running but I'm thinking we should
have a higher level of security on the server when Exchange is running. We do
not have the Windows Firewell activated on the server and it's my
understanding that you can't run the firewall on the server with only 1 nic.
Is this so? Thanks for your continued help.

Hello coopfab,

You have to devide between ICS and the firewall itself, of course you can
activate the firewall with one NIC. ICS itself require multiple NICs. But
i strongly suggest to not use ICS.

With a more detailed description of your network, amount of routers, switches,
servers and roles/applications(planned) in the future we can see how it can
look in the future.

Best regards

Our network is very simple and small; 1 SBS SP2 server, 1 router, 4
workstations. Workstations do word processing, order entry, manufacturing
database software, email, internet surfing. Basically light stuff. No major
changes planned for the foreseeable future.

Best of all is two nics teamed using the hardware vendor's teaming software.
That gives you resilience for a nic failure (and it is inexpensive). Next
best is a spare nic, ready to use, but Disabled.

The whole business about two separate network "connections" (as distinct
from two nics) is from when networking equipment was expensive and Windows
provided a simple Dial-up Remote Access Service. Then windows has to Bridge
the two networks, inside and outside.

The other specialised case for two connections is when you are using the
server as a hardened firewalling or proxy appliance, for example running ISA
server.

Then SBS Premium has configurations with two connections because it is
trying to give you everything in one box.

Now networking equipment is inexpensive and there is little reason to use
the server for remote access, connection sharing etc. Of course you may
still choose to.

Hope that helps,
Anthony

Hello coopfab,

You should connect all machines to a switch and the switch with the router.
So no need for a second NIC. On the SBS configure in DNS a forwarder to your
ISPs DNS server, all domain machines should use only the domain DNS as preferred
on the NIC.

For additional questions i suggest you use the SBS newsgroup, because lot
configuration settings are different from "normal" server versions.

microsoft.public.windows.server.sbs

or

http://www.microsoft.com/communities...ows.server.sbs
