ok,
el systema que yo uso esta en ingles.... asi es que la configuracion puede ser un poco diferente.
si quieres los pasos a seguir puedes abrir un autocad de otro computar oprimes la tecla magica (F1) buscas licencia, y de alli modificar. esto te dara todos los pasos a seguir.
ademas, no se si instalaron el network license manager. si no, tendras que instalarlo, a lo mejor esto elimine tu problema. (igual que antes (F1) para seguir los pasos de installation.
espero esto te ayude.
