I'm 2 days finding how to install isa 2004 with nlb in multicast mode due to teaming cards. I found that is the only mode that teaming cards can work with nlb in non-integrated mode. But, does anyone know how to do this?
I set the nlb on the first isa server, and when i go to connect to the second server it's impossible. Simply it denies to connect. I've tried to stop firewall services and it doesn't work ...
Certainly, I had the same problem. I suppose that this is due to ISA restrictions.
My solution was to deploy windows NLB before install ISA Server. I don't know if it will be able to change NLB settings after installing ISA. So, be very carefull when configure NLB settings to avoid problems later.
(1) Configured NLB on 2 W2K3 SP1 nodes (2) Tested NLB (all working as expected) (3) Installed ISA EE on Node 1 of NLB cluster and NLB stopped working (I certainly couldn't get NLB Manager to connect to both Nodes of the cluster, NLB manager keeps reporting NBL not found on the node that NLB Manager is not run from)
This is now driving me insane do you perhaps have a list of the rules you applied to make it work, if you can help I certainly owe you a few beers
I identified the problem as being a Microsoft one (I actually found the Microsoft statement somewhere)... That you are unable to cluster 2 servers and have any network cards within those servers teamed (some low-level hardware communication failure something (the word escapes me right now)) - this problem is true for any cluster/team situation... Not only ISA.
Once I broke my LAN team (even though this wasnt the communication between my cluster), I had absolutely no problems clustering the 2 servers.
FYI: So each of my servers have the following config: LAN1 = 172.18.x.x LAN2 = disabled (should have been teamed with the above) NLB = 192.168.x.x (heartbeat cross-over cable between the 2 servers) WAN = x.x.x.x
And of course I have an additional Config Storage Server on my LAN (running on a virtual machine actually) - as you are unable to have a CSS on a clustered ISA server
