Thing is, I had been using SQL developer tools and visual studio and then just loaded SQL report services. I work in a corp environment and cannot change the SQL Server corp configuration -- but also wanted to load a local server for learning Reporting Services. Once I removed the local installation, my ability to access the corporate accounts was restored.

However, I need to reload and be able to access both the corporate and local "instance?".  I need some pointers on how to proceed.

Thanks for the answers above, they were insightful.

I needed to do additional research.
