Hi please correct myself regarding SCCM service account how many group required for e.g sccm server admin and sccm admins again how many accounts required for e.g svc-sccm and svc-sql this needs to part of which groups? It is required to add any user or group to default group sms admin group. if any account needs to part of administrator or domain administrator? Please be specific this is bit confusing here two things are there sql and SCCM scenario like simple primary site with secondary and distribution point setup

Not as confusing as this question. What exactly do you mean?

Thanks for quick response please let me know about service account and groups used in installation of primary site? SCCM server installation and SQL installation so it requires 2 service account and these needs to part of deafult SMS admin gurop? i am looking simple accounts, groups, sms admin group 

The account needed to run the installation needs to be local admin on the server and sysadmin on the SQL.

Your SQL service account needs 'Log on as a service' right via GPO (either domain or local)

sysadmin on the SQL means SCCM server should have sysadmin access or permission or service account used for sql installation?

sysadmin on the SQL means SCCM server should have sysadmin access or permission or service account used for sql installation?

SCCM Ghost you have asked this exact same question in this post!
