When working with PowerShell I got an error. First I thought I am making some kind of a mistake because I am new to this as well 
So I was struggling to make it happen and finally figured it out. The solution was to have administrator privileges to run PowerShell. So when you want use PowerShell don’t just click on it. Right click and Run as Administrator
Bingo! Now you can use it.

This error message came when I was installing SharePoint Server 2010. You might not get this error all the time so first I’ll explain my environment which I tried to install SharePoint 2010. My OS was Windows Server 2008 R2 Standard 64-bit (6.1, Build 7600) and SQL Server 2008 Standard x64. So I started with SQL server which was a smooth installation and then started the SharePoint Server 2010. The setup installation went smoothly. But when it comes to the SharePoint 2010 Products Configuration Wizard, it asked the database server and credentials. So I gave the same name and credentials which I installed before. Then the error came
So I download the SQL Server 2008 Service Pack 1 and installed, restarted and tried again. Then I got the same error but the version number was different.
Went through everything again and finally found the solution. It was to install the Cumulative update package 2 for SQL Server 2008 Service Pack 1 on SQL server 2008.
