How to check which roles are installed on a Windows Server 2003 with cmd.exe?

Question

If I log into a Windows Server 2003 and I want to check with cmd.exe which roles are installed, how to do that?

Answer 1

The concept of roles like in Server 2008Rx does not really exist in 2003. Extra features are know as 'Windows Components'.

The Windows 2003 implementation of a RADIUS server is called 'Internet Authentication Service', to find out whether this service is running open a command prompt and type:

net start | findstr /c:"Internet Authentication Service"

if the service is running, the command will output:

Internet Authentication Service

if not, it wont output anything.

If you are using a third party RADIUS server, find out the name of it and query for that.

net start

by itself gives all all the running services.

If the service is installed by not running, it is slightly more complicated:

Find out the internal name of the service, open

services.msc

Find the service in question, "Internet Authentication Service" and show the properties, the General tab has the service name, in our case: 'IAS'

back on the command line type:

sc query IAS

if it is installed you should see something like this:

SERVICE_NAME: IAS
    TYPE               : 20  WIN32_SHARE_PROCESS
    STATE              : 4  RUNNING
                            (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN)
    WIN32_EXIT_CODE    : 0  (0x0)
    SERVICE_EXIT_CODE  : 0  (0x0)
    CHECKPOINT         : 0x0
    WAIT_HINT          : 0x0

If it is not installed, you'll get an error:

[SC] EnumQueryServicesStatus:OpenService FAILED 1060:

The specified service does not exist as an installed service.

If the 'role' you are looking for is not using a Windows Service, than you have to look elsewhere. You can get a list of installed software using a script with WMI.

Or you can use PsInfo:

psinfo.exe -i

to list all installed software, then again you can use findstr too look for the software you are after.
