I've been given an old server by a mate who was having a spring clean. I've installed VMware ESXi on it and I have a couple of 2008 server installs plus some Win7 client installs for testing and playing around with some server stuff that I can't easily test at work.

I have the old Win7 Loader but can't find anything to reliably activate the server os. As I'm going to be playing with these on and off over time, I'd rather activate them and only rebuild them when necessary.

There seems to be quite a few activators out there, I've tried about 4 versions of KMS Pico and a couple of others this evening but none of them seem to fully work.

I just wondered what everyone else is using, or if someone could PM me a link to something realiable please?
