Staying Connected

There are many companies in the world that have offices in remote locations. Sometimes downloading software media from Microsoft or Oracle might take minutes if not hours. During this time, your terminal session with the remote computer might time out. How do you prevent this from happening? The windows server operating system allows two concurrent remote desktop (RDP) connections. However, there are out of the box settings that automatically determine idle session limit and when to disconnected a user. I am including a link to MSDN that describes remote desktop…

Page Anatomy – Part 2

Finding Database Info

If you are a production Database Administrator (DBA), you might be lucky and have all your servers on the same revision of SQL Server. This is a very uncommon situation since many third party vendors do not keep up with Microsoft releases or your company might not find the return on investment (ROI) for having the lastest software. My company falls into the later category. We have some business applications that are bound to SQL Server 2000. Since it is not broken, the company is not willing to fix it….
