Network administrators like learning about new tools and being in the know about the issues likely to affect their network management. The top posts of 2009 reflect those concerns.
#1 Convert PDF files to other editable formats with this tool
Derek Schauland wrote about an application called Able2Extract that allows PDF documents to be converted to other editable formats, such as Microsoft Word, Excel, or PowerPoint, as well as Open Office, RTF, TXT, and HTML. TechRepublic members love a handy tool! Read the original post

George Ou's tutorial on IP subnetting first appeared in the Network Administrator blog in March, but it was actually a reprint of an article that he wrote in 2006.
