I need help on configuring Biztalk 2004 load balancing.
I am not talking about NLB.
Is there any configuration in Biztalk for load balancing?
Please do revert back at the earliest.

First of all, there is no single switch "load balance", you simply need to understand what you are doing. See the previous posts on this blog, it's explained there in fine details.

Very short: you don't have to load balance BizTalk server because bu itself it is stateless. You just throw more boxes in a row, and that's it. But individual adapters is a completely different story, and - don't forget! - BizTalk is supposed to connect to virtually anything. It means that adapters may have a very different set of idiosynchrazies. That's what you have to load balance, and each of them may require a different approach to load balance. It's not BizTalk that you have to load balance, it's the transports that you use and adapters for those transports. Makes sense?

So, load balancing BizTalk depends on what you connect to and how. Again, see previous posts on that. Also, you may have to load balance SQL Server with message boxes. Basically, you add more machines with message boxes, and that's it. In BizTalk 2006 you may also make primary message box dedicated to routing, that improves the throughput. See Lee's blog on that.

And, I'll forward you email to BizTalk team (remember? I am not there anymore!). They'll answer you more if they have something to add, but considering that your question is very generic, that's probably it.
