Okay, I am currently interning for a small it company and my boss had asked me to find a way to do the following:

He bought us a new server so we could play around with it. This is the task that he assigned me and my co-worker:

First, to install W2k3, which we were able to do successfully.
Second, install VMware Server on it with a copy of W2K3. This is where we are at right now.

He wants us to build a Small business server so we could start hosting exchange on it and become network admin for his business. He gave us the server so we could go on the virtual machine and start adding users and make it similar to what he does with his clients now.

However!!! I do not know how to do any of these. He said he wanted us to make our server separate from the company network. Semething about static ip and then have us remotely connect to it like how he does it with his clients. NO IDEA. Someone please help me or ask me questions so i could research more on this, or help me ask the right questions so i can get this started. Where we do start? We couldnt give the server its own ip address and separate it from the business network so it doesn't intefere with clients.

This is something experienced consultants get paid good money for and I recommend your boss do just that. A business network, especially if it deals with customers' personal information such as credit cards, and the company's tax receipts, inventory, etc., must be secure and robust. And this is what consultants get formal training for.

In the mean time, your search engine is your friend.
