"Stacking" NTLM Authentication
This question came up today (well, actually, it was about four weeks ago I started typing this, but bear with me), and it's been a little while since I've rambled about authentication protocols, so let's enjoy a nice, calm discussion on a Monday Tuesday Read More...
SetSPN improvements in Windows Server 2008! W00t!
All this stuff is based on a prerelease (RC1) version of Windows Server 2008 and may change before final release. Cheques may not be honoured. I had a happy moment one night in India when the trainer for our IIS 7.0 TTT course discussed some of the Kerberos-related Read More...
401.3, you say? Not 403?

Tip o' the Week: WEVTUTIL for EVTX/EVT file conversion
This week, a pointer to a solution to a problem I occasionally hit. Windows Vista (and by extension Windows Server 2008, I assume) utilizes a new EVTX log format for event log exports. It's XML-based, natch. Problem: Everyone's Favourite Log Digestion Read More...

Every Windows Admin Should Know: Template User vs Mr Nobody
Raymond beats me to the punch (mine was going to be rant-i-er, but five times * as funny), on how the HKEY_USERS\.Default , despite having the word "Default" in the key name, isn't "The Default User" from which all others are initially spawned. It's possibly Read More...
I want to publish a website to the Internet. How do I enable Kerberos?
Ya don't. You can't win. But there are alternatives to fighting. Why Not? Windows Kerberos doesn't work in an Internet scenario, it's intranet-only. the client machine must be a member of the same Active Directory forest as the target site. You just can't Read More...

Netmon 3, Now With Added Blogging!*
Though it might technically be possible, it's probably quite difficult ("quite" in the "very" sense) to blog from Netmon. Doesn't stop us rolling out the most significant new version in, oh, years, and the Netmon team have started a blog with tips and Read More...
