I have been a web designer and Linux systems admin since 1995. I am a life long geek and designed my first website at the at of 8, in a time before the HTML standard. I hold multiple IT certifications that I can tell you about if you are interested. However I encourage you not to base your choice on certifications alone. Experience is worth more than just the knowledge to pass a test and get certified.
If you are running any version of Microsoft Windows in a server application, please seek help elsewhere, unless you are looking for help in transitioning into a more adequate operating system. While I am knowledgeable in Microsoft desktop and “server” operating systems and applications, I do not think they are ever the best choice, and I will not work with them on a professional level.
