Dear All,
When i am trying to create the EDRSMS database for very first time, then i am not able to connect to my SQL server database, as shown in the following attached.

I have done the following steps.

The EMC Documentum Repository Services for Microsoft SharePoint Configuration menu
appears.
3. Select Create EDRSMS Database.
The Create EDRSMS Database page appears.
4. For an initial deployment of EDRSMS, select the option to Create New Database.
5. Enter the SQL content server name in the Database server name field. (getting error here)
Kindly help us.
Thanks in advance.
