The reason behind the error

  • The new server has not been added to the domain of SharePoint 2010.

The solution for Fixing the Error:

Before going through the procedure for resolving configuration error, first, check whether the following criteria are fulfilled or not:

  • All permissions related to accessing the SQL database are granted.
  • Check and validate whether the SQL database is in running mode.
  • Microsoft SQL Server to be accessed is not blocked by Firewall.

If the above-mentioned criteria are not fulfilled, then we need to successfully fulfill these criteria first and check whether the error still occurs or not.

If the occurrence of error continues, then go for the below-mentioned solution for fixing the error:

For connectivity between SharePoint and Microsoft SQL server database, check whether the status of the SQL database is in running mode or not. If not then change its status to running mode, else continue with the next step.

The internet connectivity of your machine must be proper and there should be accurate mapping in between the servers involved in it.

Check and Validate whether the Internet Information Service (IIS) manager of your PCs is not in isolation mode. However, if it is in isolation mode then remove it from that mode.

If the server is newly added to the domain, then check whether it is configured properly or not by analyzing the computer management of your machine.

After completing all the above-mentioned steps and if the error still occurs, then first uninstall the pre-installed service pack of the SQL server and then again re-install it because the cause of this error may be due to improper installation of the service pack.
