MMC only comes to yellow status and then turn back to grey

Hi,

I have installed the 7.0 trial with no problems. However, when I try to start MMC it turns yellow for a while and then stops again.

I get 2 messages in the MMC log:

1. Warning: SAP-Basis System: Stop Workproc 6, PID 4500

2. Error: SAP-Basis System: Initialization DB-Connect Failed, Return Code 008192

Any help with this is much appreciated.

Thanks.
