No authorization to logon as trusted system (Trusted RC=0).

Hello

Sap Solution Manager runs on client 500... I have 3 differents systems SCM . The dev (DS1) runs on client 140 , the qual (QS1) on client 500 and the prod (PS1) on client 500..

For the systems which have the same client (QS1 & PS1) no pb..SMT1 and SMT2 are OK.

For SSM , when i try SMT1 for DS1 it's OK

For DS1 when i try SMT1 for SSM it's OK;

For SMT2 , i have the msg "No authorization to logon as trusted system (Trusted RC=0)."..

I have applied the note 637429 & 128447 but i have always the pb..

Thank you for your help
