How to install a network printer on all workstations for all users from Windows Server 2003 Standard Edition

There are various "hacks" that can be used to populate "network" printers as "local" printers on client computers (using a "Local Port", pointing the client directly at the print device, running an LPR queue on a server and pointing clients at that). I'd recommend none of those because the ongoing maintenance is a real pain.

Assuming you have an Active Directory domain you can use Group Policy to deploy printers. This gives you a nice way to make changes, down the road, when (inevitably) you have to add / move / change printers.

If you don't have an AD domain I'd consider writing a script to "connect" to the printers and putting that script into the All Users "Startup" folder of the Start Menu. The gist of a such a script would be something like:

Option Explicit

Dim objNetwork
Set objNetwork = CreateObject("WScript.Network") 

objNetwork.AddWindowsPrinterConnection "\\server\printer-share-name"
... continue ad infinitum ...

You can also use such a script to remove "stale" printers later when (inevitably) you add / move / change printers.

I am assuming that the server in question is not a domain controller.

Log onto the server in question as a domain administrator.
Click on Start, Right click on My Computer and choose manage.
Expand "Local Users and Groups"
Click Groups
On the right hand side, double click administrators.

EDIT: Yes it is a DC...
Log onto the server in question as a domain administrator.
Open Active Directory Users and Computers.
In the domain there should be an OU called "builtin".
In that OU there should be a group called Administrators.
Double click that group and check the members of it.

I'm sorry I can't be quite as step by step with this, my DC is server 2008 and I can't remember how similar they are.

Any one in this administrators group will have permission to install programs.
