I perform centralized desktop management for a large government organization where there are a lot of disparate Domains and Workgroups. I am writing a VBScript that needs to know if a computer is in A domain. Since I may not know of all the domains involved, I can't do a compare-to-known domains and that guarantee a factual result. Knowing how to find out if a user or group account is in a domain already. And that it is relatively simple, as shown below... Dim oGroup, oParent, sResult Set oGroup = GetObject("WinNT://<groupname>,group") Set oParent = GetObject(oGroup.Parent) sResult = oParent.Class ' The returned string determines the source of the user or group. ' "Domain" = A Windows Domain ' "Computer" = A Windows XP/2003/Vista computer. ' "User" = A 2000/NT Computer (odd, but true). I thought that this would work exactly the same for a computer.... Dim oComputer, oParent, sResult Set oComputer = GetObject("WinNT://<computername>") Set oParent = GetObject(oComputer.Parent) ' This will be an IADs Domain Object. sResult = oParent.Class ' oParent.Name would return a string with a Domain or Workgroup name. ' So, sResult SHOULD contain a class string of Domain or Workgroup. ' But sResult will contain "Domain" regardless of whether or not the ' IADs.Domain object contains a Domain or a Workgroup. Since this didn't work, I browsed the IADs Class Library and found a method in the IADs.Domain object called "boolean IsWorkgroup()". Thinking I had found the solution I called the method bResult = oParent.IsWorkgroup() and received a runtime error "Not Implemented". I checked MSDN and the description for this method is "No Longer Implemented". So I am back to square one... So far the only thing that even comes close to what I am looking for is to query WMI - Win32_ComputerSystem and get the "DomainRole". Results for that can include "Standalone Workstation" and "Standalone Server". However, will this information be as reliable/up-to-date as something I can get from ADSI? Any ideas? Thanks...
