Network Load Balancing MSMQT and/or BizTalk in multi-server env.

| What is the correct, or best, way to achieve Network Load Balancing for MSMQT
in BTS2004?
I found this post from this newsgroup dated 9/20/04, which sounds like it
worked, but am wondering if this is the way to attempt NLB, or is there a
more proper method?:
The problem is that I'm using a hardware load balancer and then the
virtual IP adress is not known on the BizTalk boxes.
But I found a way to change the BizTalk Group name :-) and now it
works.
I made 2 changes in the database and about 12 changes in the registry.
Standard BizTalk uses "BizTalk Group" as a group name, that's not so
luckily choosen because I can't use that name in the DNS. When I
changed it to "BizTalkGroup" and point in the DNS the name
BizTalkGroup to the load balancer it works. It is now possible to
connect to the MSQMT using DIRECT=OS:BizTalkGroup\private$\<queue
name>.
The above is a similar situation to ours. We use cisco load balancer
equipment, and have three soon to be production BizTalk 04 servers.
Any information or documentation would be most appreciated.
Thanks,

| Whenever you are using NLB, use DIRECT=TCP instead of DIRECT=OS:, that will
get rid of the group name issues.
Also, please check that the NLB doesn't use NAT (network address
translation). MSMQT and MSMQ do not support NAT and will not work with NAT.
