Two NICs

Server config is a Terminal Server with an Exchange Server (both 2003). The

IP config is using all fixed IP's with no DHCP at all, the internet

connection is a static ip with RDP forwarded to the TS.

The internet connection is ADSL but the user has purchased a 20mb cable

connection with a view to improving communications performance and wants to

have both connections active. NLB is not required.

 

Can I just add the second nic, connect it to the cable router, and use a

fixed IP on the same subnet as the ADSL router?

ADSL router 192.168.1.1

Cable router 192.168.1.254

TS Server 192.168.1.5, gateway 192.168.1.1 on one nic and 192.168.1.253

gateway 192.168.1.254 on the new nic.

Exchange Server 192.168.1.6 gateway 192.168.1.1 running DNS and WINS

Seems too simple and I am sure I have overlooked something. Any comments or

input much appreciated!

Aggregated? I don't know how well this is going to work given that it's ADSL

and cable.

Don't use two NICs - it isn't recommended in a DC and won't do what you want

anyway. Instead, get them a router that has two WAN interfaces and can

handle this seamlessly. Actually, rather than a straight router, I'd check

out the SonicWALL line - you haven't mentioned what your firewall protection

is.

 

Inbound connectivity will be more problematic than outbound - you may need

to get a dynamic DNS service such as DynDNS (even though you've got statics)

and access your TS / Exchange via a dynamically updated hostname.

 

PS: I presume you mean your network has a single DC which also runs

Exchange, and the Terminal Services box is a member server....if so, that's

a good setup,although it's best to run Exchange on a member server if at

all possible. In a small office this can't always happen. Just don't run

Exchange on your TS box (or vice versa) and don't make your TS box a DC or

anything besides a TS box.

 

PPS: It's always going to be presumed that anyone with a lick of sense uses

static IPs on their servers, so that isn't really worth mentioning....if you

mean you use static IPs on your workstations, it isn't relevant here,

although I would question the wisdom of that as DHCP is so much easier to

manage.

Hello ratman,

 

I would not configure a TS with real server tasks like exchange or a domain

controller. They should be run as dedicated machines and do nothing else.

For additional background the Exchange Server is the DC and the TS just runs

TS. There are only 6 users who all use RDP; the servers are located at a

private address for hardware security reasons.

No option with the static IP's; the cable provider does not provide static

so will be using DynDns for mapping.

Excellent.

Even more so. And even more reason *not* to multihome this box.

That wouldn't help you host multiple resources requiring the same listening

ports, if you cared about access from the internet!

 

If the company decides they want to move forward with this someday, they

will probably need to look into leased lines.

You're welcome - glad you're off the hook.
