Okay, I'll admit this may be child's play to some, but I just ran across an issue I didn't know about - I was prepping a Windows 2008 server for an installation, and needed the MMC on it. So I went to the MMC download page and tried to install the program (if you know what's coming, please don't mock me). I received a (unhelpful) error message that "Not enough storage is available to process this command".
Interesting. This was a brand new server, so I checked the disk space. There's TONS of available disk. What the heck?
I then did some digging around on the internet, without finding much, except this Microsoft KB article - Misleading error message when you install an update package in Windows Vista or Windows Server 2008: Not enough storage is available to process this command. Not much help there, if I'm getting the error message I'm going to assume that I have the wrong version. And no help on how to fix the problem. Frustrating.
Well, then I did what I should have done in the first place, and asked my co-worker Tim if there was a trick to installing Microsoft Management Console 3.0 on a Windows Server 2008 machine. He quickly (and politely) schooled me by replying, "Umm.. I thought that 3.0 was built into 2K8".
Oh.
