Solution Manger 7.1 SUM Upgrade Error

Dear Experts,

During SolMan Upgrade 7.1 from SP10 to SP14, I am struck with the error in Preprocessing step "phase MAIN_SHDRUN/START_SHDI_FIRST! " (see attached screenshot).

I tried to start the shadow instances services from the windows server. But, I get the error message "Windows coud not start the SAPSID_04 service on local computer. Error 1069: The service did not start due to a logon failure."

Any ideas, please?

Thanks & best regards,

Sreenu
