Hey trinaytech,

This blog post by Mitchell Sellers may be of help to you. Installing DotNetNuke 4.7.0 on a Remote Host (older version of DNN, but principles should still apply).

From the post:

Configure Database

DotNetNuke requires a SQL Server database to operate and this is something that must be configured.  Depending on your hosting provider the database and database user account might have already been configured, if not you might need to create the database and user.  The point of this step is to ensure that you have the following informaiton for your environment.

• Database Server Name (The name/ip of the server where your database resides, never include HTTP in the name)

• Database Name (The name of the database where you can store information)

• Database User (The user account that you may use to access the database. NOTE: this account should have DBO permissions)

• Database Password (The password for the username listed above)

You can obtain the Database Server Name from your hosting provider, most of them provide this information on their support sites. This value might be a fully qualified domain name (db1.3essentials.com) or as an ip address (10.12.12.5) or potentially a few other styles of values depending on their configuration. The remaining pieces of information all relate specifically to YOUR databaase on their server. If you are using Plesk you can obtain all needed information from the "Databases" section of your control panel.

If you are unsure of where to obtain this information contact your hosting provider.
