MTS2.0 with MSCS

I have been tasked with configuring MTS 2.0 in an NT4 sp6a cluster. Does anyone have any experience with this? Perhaps some “gotchas”. Also, looking at Microsoft’s MTS documentation it states to install Windows NT QFE Q116844 to fix a RPC problem. However, I can’t find this anywhere. Does anyone know if installing SP6a resolves this problem? TIA
