Through the use of REGEDT32.EXE you can verify the role of the installed Windows NT.

MORE INFORMATION

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

Using REGEDT32.EXE, find the following registry entry. 

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ProductOptions\
   ProductType
ProductType can be one of the following: 

WINNT    = Windows NT workstation
LANMANNT = Windows NT Server domain controller (primary or backup) SERVERNT = Windows NT Server stand-alone

Do NOT change the ProductType under any circumstances. Changes to the ProductType can result in the failure of the Windows NT operating system.
