BHOLD Core Installation database errors

I am trying to create a test lab for BHOLD. I have followed the instructions in http://technet.microsoft.com/en-us/library/jj134095%28v=ws.10%29.aspx

No matter what options I try, I was unable to install BHold Core if I supply the db details when db is on a different server, the installation would fail.

Error -2147217843: Installation failed to create the database B1.

Could someone help?

Thanks
