I'm having trouble setting up a NLB cluster - my setup
The network of 60+ clients lives on IPs 10.1.2.x
The servers (AD, DNS, DHCP, DFS-R etc) live on IPs 10.1.1.x
Subnet mask on both clients and servers is 255.255.0.0
Gateway is 10.1.1.1
2 windows 2003 servers, (call them A and B) each had 1 network card - A is 10.1.1.21 and B is 10.1.1.22
A and B are file severs hosting DFS-R shares (replicated with each other)
A is also the Print server for the network.
I installed an additional network card into each server and began to configure each server using the NLB snap-in.
I configured A such that card 1 was untouched (10.1.1.21, 255.255.0.0, 10.1.1.1)
and card 2 is (192.168.1.200, 255.255.255.0, no gateway) added to a new unicast NLB cluster called "cluster" on 10.1.1.19
I added DNS records such that 10.1.1.19 points to cluster - from domain PCs and server B I can ping A, and ping cluster OK using both hostnames and IP addresses.
So far so good...
On B I configure the 2nd card as 192.168.1.201, 255.255.255.0, no gateway.
Back on A I right click the cluster in the NLB manager, put B in the host box and choose the 2nd card (the 192.168.1.201 card). I left the priority at 2, and clicked finish.
After a few moments B is shown as pending and then unreachable - now the problems start - I cannot ping B from A via ip address or dns name. B cannot ping A via IP or DNS.
When I ping A from A using hostname, it replies on the 192.168 interface, not the 10.1 interface
I can open the NLB management snap-in on each server, and it will show that that server is part of the cluster, but the other server is unreachable.
Any help will be appreciated
