A. Several Windows NT installation types exist, such as NTWorkstation; NT Server; NT domain controllers; NT Server 4.0, Terminal Server Edition (WTS); and NT Enterprise Edition. To check the installation version, type
net accounts
However, this command sometimes won’t give all the information. Another way to check your version is to look in the registry. To do so, complete the following steps:
Start the registry editor (regedt32.exe).
Move to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlProductOptions.
Look at ProductType, it will be one of the following types:
WinNT - Windows NT Workstation
ServerNT - Windows NT Server standalone
LanmanNT - Windows NT Server Domain ControllerYou can also look at ProductSuite (if it exists), and depending on yourversion, you might see one of the following types:
Terminal Server - WTS
Enterprise - Enterprise EditionClose the registry editor.
If you attempt to open or edit these values (depending on your service pack), the OS gives you a warning and changes the value back to its original setting. Don't try to change these values.
If you don't want to search the registry,WinInfo (fromhttp://www.savilltech.com/download/wininfo.zip)displays the product type (and much more), which will be one of the following versions:
NT Workstation
NT Server
NT Domain Controller
WTS
NT Enterprise Edition
