Generic Troubleshooting: "Is it still a problem?"
I've been doing this support thing for a while now. Frequently, the basics are what get overlooked when troubleshooting an issue, particularly an issue that seems complex on the surface. Often, though, you'll find that the detailed techniques lead you Read More...
The Cat's Out Of The Bag: ISA Server will become ForeFront TMG
So, we all know that ISA 2006 doesn't work on Windows Server 2008 . Massive architectural changes to the IP stack, blah blah, etc, etc. People (uh, yeah, just "people") have been asking about what's to become of ISA Server for a while: "There's Read More...
Post-SP2 TCP Offload Fix
I've mentioned Chimney before . Now, a new Windows Update fix for TCP Offload, which turns it off . It was on by default in Windows Server 2003 SP2, so if your NIC supported Offload, or RSS, or that other thing I can never remember, it was enabled. But: Read More...
IIS7 Modules Aplenty - WebDAV, Bitrate Throttling
New modules, supported by Microsoft, are now officially RTMd (RTWd?) and available for use with IIS 7.0. WebDAV Yay new WebDAV! Yay being able to enable it on specific parts of a site! Yay better!

"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...
MaxUserPort - what it is, what it does, when it's important
What can we say about MaxUserPort that hasn't already been said? Not a lot, it would seem. He's a beautiful dancer, perhaps? Ahh, such gentle humour, and nary a kitten drowned anywhere. But TCP port shenanigans are fairly frequently misunderstood, so Read More...
What's in IIS 7.0 for me?
While having a seemingly-innocuous chat with a colleague, I was asked to "throw together a few points" on what IIS 7.0 would do for a web application I've worked with in the past. Serves me right for talking to people , really. In this application's 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?
You're running an IIS 6.0 website, and you have a virtual directory configured for anonymous authentication only (that is, you've un ticked Integrated Windows Authentication). Using a web browser, you try to access a file in that virtual directory. http://example.com/vdir/something.txt Read More...
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...
Jason Brown's new blog
The traitorous malcontent (and former MVP) that left my cubicle for greener pastures has set up his own (shiny! new!) little shack on the intarwebs, discussing Sharepoint of all things. I mean, I know he's in the Sharepoint support team now, but honestly Read More...
Netmon vs Chimney
I recently encountered TCP Chimney for the first time in the wild. Short version: Chimney is an offload technology that allows the NIC to deal with up to X TCP connections, with any overflow being handled by Windows. All good: get the NIC dealing with Read More...
Generating a memory dump when a particular event log occurs
Building from Paul Long's post on stopping a Netmon3 capture on a particular event , we're going to re-jig it so that we can run ADPLUS soon after a particular event is logged. This won't produce a dump at the exact moment of the event log (which more Read More...
KDC_ERR_BADOPTION when attempting constrained delegation
Hit this earlier while working with someone else on a Kerberos delegation problem. All the SPNs looked right and were registered against the right accounts; all the App Pools were Network Service; from what I'd been told, everything should have been working... Read More...
