You want to move off of a hosting company and onto your own server, and your own server is Win2K? I wouldn't spend the money to move anything to Win2K.

There's a lot of info you're not providing that makes this a challenge.

1) Is this a mission critical app for you? If so, why do you want to move it?
2) What version of Server and SQL is it currently running on?
3) Do you own MS SQL Server in the version that your DB uses?
4) I am not even sure if SQL 2K5 or 2K8 will run on Windows 2K, so you better check that.
5) Do you know what development tools are used to support your database? Visual studio, etc?? Do you own those? Are the compatible with Win2K?
6) Does it run a webserver? If so, what version?
7) Who owns the domain?
8) Who is the domain admin?
9) Who hosts the DNS?
10) Do you have a static IP addresses in your office? Are there addresses available?
11) Do you have a firewall?
12) Who maintains the firewall? Can they make the changes needed to support the webserver?

There are many more questions that need to be asked, and they will spawn questions and so on. If you don't know the answers to these, then you should stop and get these answered before you try and move this thing.

When you ask computer people if something is possible, it's like asking your Porsche mechanic if they can make it faster. The answer is almost always yes, but you may not like the costs.

Good luck.
