For the morbidly curious, in support of the LCS 2005 Migration Document project, I have been building (yet another) lab.
As of now, I have a fully functional (no PSTN :( ) LCS 2005 SP1 pool, Access Proxy, sited behind an ISA 2006. And it connected first time through from my home network via the AP.
All this goodness running under Hyper-V.
Servers are ws03 r2 sp2.
Client is currently OC2005 on XP and OC2005 on win7beta.
A few notes:
WS03 r2 SP2 breaks ISA 2006 (I had forgotten). This requires two separate reg hacks (disable RSS and Task offload)
Hklm\system\currentcontrolset\services\tcpip\parameters [dword EnableRSS = 0] [DisableTaskOffload = 1]
DNS stinks for LCS.
Certs came from a standalone CA on the DC. An enterprise CA would not give me private keys on the certs unless I moved the DC to Server Enterprise which I was unwilling to do.
It is amazing what we have to re-learn at times, eh wot?
