How to restart TM1 Admin Server service after a crash or a hang without impacting running TM1 Servers ?

Question & Answer


Question

For some reasons it might happen that the TM1 Admin Server either crashes or hangs.
In such a situation, if we try to restart the "IBM Cognos TM1 Admin Server x64" service through the Windows Services tool (services.msc), we get two annoying behaviours:
-> If the TM1 Admin Server has crashed, we get the following error message when trying to restart it : "The IBM Cognos TM1 Admin Server x64 service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."
Or
-> If the TM1 Admin Server has got hung/frozen, meaning that TM1 Servers cannot reach it anymore for some reason, thus TM1 Servers cannot be registered anymore by TM1 Admin Server,
then restarting the "IBM Cognos TM1 Admin Server x64" service would also restart all running TM1 Servers, which we want to avoid at all costs.
How to restart TM1 Admin Server without having to restart all TM1 Servers that depend on it ?
