Windows 2008 R2 Domain Controller - Multiple NICs
Posted on 2011-03-01
I've recently completed my first Windows 2008 implementation as our new primary domain controller and I'm impressed the functionality over 2003.
The file server side of things is set up with permissions/quotas, as is the fax server, AD, DNS, DHCP, etc.
All I need to do to finish this project is move over the last 1-2 roaming profiles from our old 2003 DC, migrate our standard Windows VPN from 2003 > 2008 and rollout WSUS.
The final step is to purchase Acronis Backup & Restore 10 w/universal restore (we've got a trial running at the moment).
The server seems to be running well, but I was thinking of ways to potentially improve the network performance.
As the Dell Poweredge R710 has 4x NICs, could I use the 2nd NIC (and 3rd/4th in future) to spread the load of the traffic?
For example, out of 30 users - could I split the office so that 15 connect to NIC 1 and the remaining use NIC 2?
At the moment, the NIC 1 settings are:
1st DNS: 192.168.114
2nd DNS: 192.168.1.100 (Old 2003 DC)
I was thinking of changing the NIC 2 settings to:
1st DNS: 192.168.116
2nd DNS: 192.168.1.114
This doesn't seem to work, so I just wondered what am I doing wrong? Or is it a case that Windows 2008 doesn't allow 2 NICs to be used on the same network?
It's not essential that I use 2x NICs but I'm just thinking of ways to improve performance and balance the load across the 2.
I look forward to your replies, and thanks in advance!!
