If you said that to VirginMedia employees they would take that chance to lie that you should be on a business line :P And tell you its about 200 quid a month.
They actually tried this with me years ago, I had a server running which was tied to my till at my store (sold it a while back), they tried to get me on a 50mb dedicated line.. that was until I told them to shut up in not so many pleasent words.
They heard business and till and thought I was running my business from home, but I wasn't it was a simple stock checking program I ran when things were sold my program would warn me if I needed something restocking. Not running a business at all.
Anyways, I still think it would be cheaper to go to a host to do it, all the leg work is done then.
As for Windows Server 2008 not being legit, be careful, MS are in the process of making ISPs tell them about digital signatures of OS's and from there be able to kill your OS and put pressure on your ISP to take you offline also. Just sayin :P
Fair enough on the MS Part. As for the ISP I already have the 50mb dedicated line cuase as i said ive done hosting for years just my main box died recently. I'm going to assume i should go elsewere for help. Thanks anyways guys.
