Retire server: error 22

Hi,
I am running a French ZCM. When I try to retire a server, I get an error 22 (cannot find the object). Both these commands give the same result:

zman zsret /Devices/Servers/zcmp0.cegepsherbrooke.qc.ca

zman zsret /Périphériques/Serveurs/zcmp0.cegepsherbrooke.qc.ca

Regards,
Marc Delisle
