SQL Service Account

Dear All,

             In our environment, we have three domain account for DLO. One domain account is for DLO admin console. Second domain account for SQL installation. Third account is for DLO service account.

             After installing the DLO with SQL 2008 R2 in the local server, DLO works perfect with those accounts mentioned above. Meanwhile we supposed to install SQL SP2. After installing the same, it shows that DLO Admin service is down.

MY Query:

1) Will DLO 7.5 supports SQL 2008 R2 STD SP2?

2) SQL domain account must have sys admin rights? Please share the permissions that DB must have

Thanks,
