I'm running windows Vista and am looking for a decent VM software to emulate Windows Server 2003. Possibly an alternative to VMware, I've used it in the past and didn't have much luck getting it to work the way I needed it to.

What are your opinions?

Thanks.

Personally I use VMWare workstation and VMWare server depending upon if it is my machine or my work machine. Since Server is free I use it at home and work paid for the workstation license.

But there is always Virtual PC, I found it to be slower to do the same things I did in VMWare so I stopped using it but worth looking at.

Try Virtual Box it's free/open source
