FIX: Error message when you try to enlist two orchestrations at the same time in BizTalk Server 2006 or in BizTalk Server 2006 R2: "Value does not fall within the expected range"

When using Scott Colestock's excellent deployment framework for BizTalk, you start orchestrations by the assembly load. If these are bound to more than one host (fairly common), the first time you start them you'll run into the following error:

Value does not fall within the expected range

I read about a MS fix for this on Scott's site, duly downloaded it only to find that it wouldn't install - the fix was only for R1 of 2006 and hadn't been included in R2. A trip to MS support yielded a developed, tested and released hotfix in less than a month.
