dont want my own desktop on each computer

The question is worded oddly, but it sounds like you're talking about folder redirection.

This is likely a group policy on your server that is directing your desktop to a folder on the server, so that all your icons are stored on the server. This would need to be disabled in group policy, which would mean either disabling it for everyone, or just putting your user in an OU that has that group policy specifically disabled.

Sounds like a roaming profile.
Its a setting within your server directory configuration in AD-- Probably set by policy for all users within your infrastructure.

Configure and use the credentials for another account when logging on your servers instead of your account to keep your production and administration profiles separate.

What content are you talking about? if there are folders or icons on the server desktop you don't want to see, then you probably will not have any control over that unless you have administrative rights on the server.  Depending on how the administrator set up the server environment for you, you might be able to re-organize that content into folders so you won't a bunch of icons cluttering up the desktop.
