As far as I know only the MSSQL Enterprise edition is supported by SAP and not sure how you were able to setup a system on a Standard edition.

If this is a new installation then I would re-install the SAP system with the supported edition (Enterprise) of MSSQL. I believe there is a possibility to do an edition upgrade on MSSQL. You may try that and see if it helps.
