14 October 09 03:24 PM | tristank | 0 Comments   
Health Checks I perform ISA Server Health Checks for Premier Support (via Premier Field Engineering) as part of my role. I’ve seen something a few times recently that I thought it might be helpful to call out, while poking around in the Performance Monitor Read More...
PL15W2SP.DLL vs Firewall Client
19 August 09 10:37 PM | tristank | 0 Comments   
As I possibly misspelled or misremembered it, the PL15ws2p.dll (possible sic) file was installed as a Winsock Layered Service Provider on a couple of boxes at a customer site. Coincidentally, these machines were Windows Server 2008 machines where we couldn’t Read More...
ISA Server 2006 on Windows Server 2008: Nup
05 June 09 02:52 AM | tristank | 1 Comments   
Yuri’s blog explains some of the detail. But there’s slightly more subtlety to it, which I’ll try to snake-oil in front of you here: Can I install ISA 2006 on 32-bit Windows Server 2008 ? No , it only runs on Windows Server 2003. Okay, so technically, Read More...
On the ISA Server Security Update
15 April 09 11:57 AM | tristank | 0 Comments   
Rambling my way to a point One of my most favourite “Favorites” (read: “he snarled”) in recent weeks has been the ISA Server Product Team’s Build Numbers post . They helpfully list the version numbers of each ISA Server, um, version, along with a link Read More...

There are two major classes of Anti Virus software (yes, I know I used one word above, it’s called SEO, okay?) that can be used on an ISA Server computer: ISA-integrated antivirus scanning products Regular desktop/server antivirus products The first category Read More...
IAG – now available for Hyper-V

Of all the things I could be doing right now, blogging is the one that won. Feel special? Procrastination, but with a helpful bent. IAG SP2 is now a VHD for Hyper-V Your mission, Jim, is to make that into a song. The most interesting “wow” moment I had Read More...
The Cat's Out Of The Bag: ISA Server will become ForeFront TMG
09 April 08 05:21 PM | tristank | 1 Comments   
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...
"Stacking" NTLM Authentication
11 March 08 05:30 PM | tristank | 0 Comments   
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
11 March 08 05:17 PM | tristank | 0 Comments   
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...
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...
Netmon vs Chimney
23 July 07 02:22 PM | tristank | 1 Comments   
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...
Kerbi Wiki
12 April 07 05:35 PM | tristank | 1 Comments   
Back from another holiday (I call it the Arnold Rimmer technique) I've been trying to collect, rework and refurbish my thoughts on web-based Kerberos stuff in a personal Wiki. You're welcome to peruse it with the usual disclaimers that I'm frequently Read More...
I want to publish a website to the Internet. How do I enable Kerberos?
02 March 07 11:44 AM | tristank | 0 Comments   
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...
NLB Ain't Application-Aware
01 March 07 04:04 PM | tristank | 1 Comments   
It's been ages since I touched on anything wibbles-related , but I realized I'd neglected a very common query: If one of my applications is under load, will Network Load Balancing route/move/transfer all the additional load to the other server? No . As Read More...
