DNS or configeration problem with www.

[wee493]

Hello, I have recently setup a level 1 VPS but, I'm having a minor problem (not exactly a problem, just ocd :/ ) with the domain/dns. My site is adrianstech.com, but if you go to www.adrianstech.com you're going to notice that it takes the www. away. I would like for it to just use whatever the user has entered. if the is a www. keep and if there is not a www. don't add it.

Also I'm not sure if it is a name server or configuration problem. If it is a name server problem, below is my current Name Server setup as seen in WebMin. I tried adding name servers with and without www, but had no luck.
