Password change on Cisco 3550 Switch

While troubleshooting a switch for a client I wanted to change the configuration register of the switch to boot from a different location.

Create Outlook Form and Open with Macro

Excel Footer Images Overlap Text

It is not uncommon to use an image file for a header or footer in Excel. Sometimes these are fairly large images that you want to spill out of the header or footer region and into the text. In both cases the images seems to appear behind the text but when the image is in a footer and you go to print the image is actually covering the text on the spreadsheet. This is not a problem with the header. There is no real solution but I’ve found partial workaround.

Outlook Categories Automatically Collapsed

Recently I switched away from folders to Categories in Outlook 2010 because it gives me the ability to categorize a message multiple times rather than having copies of the same message in different folders. I then Grouped my Inbox by Category and then Received. My only problem with this system was the tendency of Outlook to expand all the categories if I went to another folder and returned to my Inbox. I found an easy solution!
