  • Windows Tip: Running scripts using alternate credentials

    Posted October 5, 2007 - 11:48 am

    On Windows XP and Windows Server 2003, you can run a program using different credentials than those of the currently logged-on user. Administrators often use this Secondary Logon feature to increase the security of their workstations by running as an ordinary domain user for most purposes such as browsing the Web and checking email. Then, when you need to open an administrative tool like dsa.msc, you either open a command prompt and use runas mmc.exe to launch the .msc file or you right-click on the .msc file itself and select Run As from the shortcut menu. But what if you want to run a VBScript script using alternate credentials? You can use the runas command from a command prompt, but unfortunately right-clicking on a .vbs file doesn't bring up a Run As option in the shortcut menu. It sure would be nice if you could add this menu option, but how? Well, where there's a script, there's a way.

  • Windows Tip: When the Clipboard Dies

    Posted September 14, 2007 - 11:43 am

    Windows Terminal Services is generally a solid platform to use in enterprise environments but occasionally during a Remote Desktop Connection (RDP) session I've had my clipboard go all wonky. What happens is I've got multiple applications open and I'm cutting and pasting text from one program to another and suddenly I can't copy anything new to the clipboard. I can still paste, but I can't copy. This seems especially prone to happen when I'm copy/pasting between an application running locally on my desktop and an RDP session with the Terminal server.
  • Windows Tip: Widening Outlook Search

    Posted September 14, 2007 - 11:04 am

    By default, when I type a search query into the Instant Search box in Outlook 2007, it searches the contents of the current folder only. So if I'm reading emails in my Inbox and I type the word "test" in the search box, the search results will display any emails in my Inbox that have the word "test" in the subject, in the From field, or in the message body. What if I want to find such messages in any message folder and not just my current folder?

  • Windows Tip: Defragmenting large volumes

    Posted September 10, 2007 - 3:15 pm

    Defragmenting disk volumes regularly is important for ensuring optimal performance of your storage subsystem, but what if your volumes are really large? Today, it's common for even desktop systems to have volumes that are hundreds of gigabytes in size, and volumes on servers can often run into the terabyte range. And if you have a storage area network (SAN), you may be dealing with even large volumes. Can the built-in Windows defragmenter handle such large volumes? In theory, probably, but in practice, maybe not.
