Question:

We are using Winbatch to run our domain logon script. I need to determine if a user is logging on from workstation or server. I don't want to SMS our servers. Any ideas?

Answer:

A "server" is any machine running the "Server" service. A "Workstation" is any machine running the "Workstation" service.

Most machine commonly referred to as Workstations or servers run both services, and thus they are indistinguishable by the wntServerList function.

If you want the "role" the machine is set up for, a "Server" role or a "Workstation" role, you have to peer into the machine's registry (do you have security privileges?), e.g.,

In order to distinguish between Windows NT Workstation and Windows NT Server, use the registry API to query the following:

        \HKEY_LOCAL_MACHINE\SYSTEM
        \CurrentControlSet
        \Control
        \ProductOptions

The result will be one of the following:

        WINNT      Windows NT Workstation is running.
        SERVERNT   Windows NT Server (3.5 or later) is running.
        LANMANNT   Windows NT Advanced Server (3.1) is running.

WIL Sample code

ver = WinVersion(4)
if ver == 4  ;if NT
   prodstring = ""
   prodoptions=RegQueryValue(@RegMachine,"System\CurrentControlSet\Control\ProductOptions[ProductType]")
	if StrUpper(prodoptions) == "WINNT"
	   prodstring = "Windows NT Workstation is running."
	Endif
	if StrUpper(prodoptions) == "SERVERNT"
	   prodstring = "Windows NT Server (3.5 or later) is running."
	Endif
	if StrUpper(prodoptions) == "LANMANNT"
	   prodstring = "Windows NT Advanced Server (3.1) is running."
	Endif
	Message("Product Option", prodstring)
Endif
