Installation ECC5+ora with MSCS

Dear experts,

We're getting a problem during the MSCS installation step MSCS Node A Configuration.

When we run this step we get an error:

"FSL-06002 Error 1722 (The RPC server is unavailable.) in execution of a 'OpenSCManager' function, line (130) with parameter (ServicesActive).

MOS-01203 Could not stop the 'SAPOSCOL' service on host '\\NOT_EXIST'

Could you help me in this issue?

regards,
Filipe Vasconcelos
