I work as a Consultant. Working with Printing software and also an important element of my day to day duties which is looking after Customer's Microsoft networks (SBS,2003,2008,Exchange....) and more importantly our own internal showroom network.
My areas of knowledge are Microsoft products TCP/IP Networking. I've experience with CISCO equipment after running through both CCNA and CCNP academy courses.
If I can help you then I will do my best to. I tend to word my answers taylored to questioner.
