1)  Open a DOS box / command prompt:  Start -> Run -> cmd
2)  Navigate to the TM1 bin directory using the cd command. Go to the TM1 bin directory, the default installation path is "C:\Program Files\Cognos\TM1\bin".
3)  Type the following command:
         tm1sd.exe -install -n"NameOfTM1Server" -z"PathtoTm1s.cfgFile"
Where the "NameOfTM1Server" (after the -n) is the name you want to give to this TM1 Server service.  If the name you are going to use contains any spaces, this value must be specified in double quotes.
Where the "PathtoTm1s.cfgFile" (after the -z) is the path to the tm1s.cfg file for this the TM1 Server you are setting up.
For example:
         tm1sd.exe -install -n"TM1 Production Server" -z"C:\Program Files\Cognos\TM1\Custom\TM1Data\PData"

If the command is successful, it will return the following message:

TM1 Server / tm1 production server installed.

4)  You can then go into the services listing, and you will see the new TM1 Server service you setup.  Following the above example, the service would be listed as:
         TM1 Server / tm1 production server
    You can then configure the service to run automatically, and to run under a specific domain user.
NOTE:  If you are setting up a completely new TM1 Server for which you don't already have a tm1s.cfg file, you can copy the tm1s.cfg from the Planning Sample TM1 Server and modify it accordingly.  At a minimum, you will need to modify the ServerName, DataBaseDirectory, and PortNumber parameter values.
If the service does not start (error message stating the service cannot be started), starting the same TM1 Logical server as a desktop application will usually provide more detailed information on the error.

Removal of the TM1 service

To remove a TM1 Server service (again, following the example above), follow steps 1 and 2, then type the following command:
         tm1sd.exe -remove -n"NameOfTM1Server"

Where the "NameOfTM1Server" (after the -n) is the name of the TM1 Server service you wish to remove.
For example:
         tm1sd.exe -remove -n"TM1 Production Server"
