Ethernet and WiFi and Bluetooth, oh my!

Customers have long requested a way to configure a computer to automatically disable its wireless NIC when its Ethernet is in use. Many third-party utilities can do this for you, but neither XP nor Vista have a built-in way to accomplish this, nor will Windows 7. Although having both NICs enabled first appears to cause…

[OT rant] Are there any home WiFi routers that DON’T SUCK?

Warning: rant ahead, and names named. When I’m not traveling, I like to work from home some days rather than endure the trek from Seattle to Redmond (although it’s much better now that our own employee transit service has expanded into my neighborhood — the existence of which is sad commentary on the availability and…

Directly connect to your corpnet with IPsec and IPv6

Contrary to popular belief, the rumors of my demise have been greatly exaggerated. Well, ok, no actual rumors, but hey, one can dream, huh?

Today Bill has a new memo, one that is very important for all of us who strive to achieve a balance between being secure and, well, getting work done. Some…

Curious about the ways Windows talks to the Internet? Here’s your answer.

I was browsing through the Microsoft download pages today — yeah, even we employees occasionally find little nuggets interspersed among the usual updates and such. I noticed a pair of whitepapers that will answer a common question I hear from many of you in emails and at conferences. You’ll want to keep these handy. Using…

Windows Vista vs. hotels

At many TechEds this year I’ve presented information about the new TCP/IP stack in Windows Vista. One of the important advances is its automatic performance tuning. With some of the early pre-release builds of Windows Vista, people were reporting problems with public Internet connections, most notably in hotels. Some of the routers used in hotels don’t…
