  • Fix a Cisco 3750 with blinking PoE light

    In this article I’ll discuss how to fix a Cisco 3750 24 Port power over Ethernet (PoE) switch with a rapidly blinking amber PoE light.

  • Fix broken images in Outlook 2003

    A strange problem exists with Microsoft Outlook 2003 where embedded images in HTML encoded messages are replaced by a red x (broken image).

  • Vista ReadyBoost and SD Memory

    I got a Sony VAIO with a built in SD Card and MemoryStickTM slot.

  • Clients get error 0x8004010F from new Exchange Server

    Recently I worked on an Exchange Server 2003 deployment project. After the server was added to the existing Exchange environment, clients kept getting error (0x8004010F): ‘The operation failed. An object could not be found.’ on Outlook. This is how we resolved the issue.

  • Replacing Toyota key fob batteries and more…

    My 2004 Toyota Corolla is a great little car. It consistently goes 38 miles on a gallon of gas and costs nearly to nothing to maintain. Recently though, there were a few things I’ve had to replace myself because the dealer just charged too damn much. The DIY maintenance procedures I’ll cover in this article…

  • Task Manager says svchost.exe uses 100% of my CPU

    It is hard to believe that this tiny (14kb) program originally created by Microsoft has been the source of so much controversy. Also known as the Generic Host Process for Win32 Services, svchost.exe has been exploited by a slew of computer worms and viruses because it is such an integral part of Windows XP. Throw…
