SCCM 2007 R2 installation and configuration on Windows 2008 SP2

Well this one was fun!
I hadn’t done a SCCM install for a while so I put my had up for an install at a small client site (100ish users).
This didn’t exactly go to plan…..to say the least.
I started off with Windows 2008 SP2 x64. The installation went without any major issues but after a reboot I the server threw out a heap of 32bit perfmon errors.
After doing a fair bit of research I ended up rebuilding the server with Windows 2008 x86.
To get SCCM installed and working on 2008 you really need to follow this Technet guide.
After this was done I configure my boundaries based on AD sites, configured my push settings and discovery method and some other  basic settings.
Now the test – I pushed out the client to a test machine.
Everything installed properly but in the configuration of the client on the test machine there was no site ID and it was not showing up in the console as having a client.
After about 6hrs of what felt like bashing my head against a wall and following and checking every single link Google threw at me I found this little gem http://social.technet.microsoft.com/Forums/en-US/configmgrsetup/thread/f9c24533-67b7-4281-ae5e-31c8f8f1da8d, and this one http://social.technet.microsoft.com/Forums/en-US/configmgrsetup/thread/6534f6ec-92a6-432b-b71b-e9e905aedaf4
While it didn’t actually have the answer to the issue. It did point me in the right direction.
I proceeded to extend the AD schema and set the site properties to update via AD and change the boundary to be IP subnet based.
I then went to bed (it was 4am at this stage). In the morning not only was the site ID in the test machine clients SCCM had been silently installing for the 3 or 4 hours I had left it for.
I was more than a little relieved when I saw this working as I really didn’t have it in me to fight with SCCM on 2 hours of sleep.
