ISA Server 2006 TCP Retransmits
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...
Antivirus software on ISA Server
09 April 09 10:44 AM | tristank | 2 Comments   
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
29 January 09 07:47 PM | tristank | 0 Comments   
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...
Home Hyper-V Networking Gotchas
13 January 09 10:12 PM | tristank | 5 Comments   
Before the holidays, I bought myself an early present: a new quad-core box with 4GB RAM, which I was going to use for a home Hyper-V lab, so that I could run a bunch of 64-bit VMs as well as the 32-bit staples I’ve been using for years (SBS 2003, and Read More...
What does it mean when there's no "broken page" icon in IE8?
10 September 08 06:59 PM | tristank | 0 Comments   
I was just catching up on some of my RSS feeds, and noticed that one of the pages I was at didn't have a broken page icon, but wasn't working quite right (some broken javascript in the photos area, I'm guessing... I'll investigate that next). I wondered Read More...
That Memory Leak Revisited
25 June 08 04:59 PM | tristank | 2 Comments   
While searching for memory leaking troubleshooting techniques that could be applied to 64-bit Windows (for the DHCP Server memory leak I found I had the other day ), I stumbled across the answer to my problem in an internal tool (weird that I missed it Read More...
Windows Server 2008 Diagnostics Off The Cuff
20 June 08 10:15 PM | tristank | 1 Comments   
A word of caution to those of you that like endings: this isn't over yet. I'm running a rather sad and noisy X64 desktop as a server at home. Once a proud warrior, actually, no, wait, it was never any good. It's just a Virtual Server host (it's not quite 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...
Post-SP2 TCP Offload Fix
17 March 08 02:31 PM | tristank | 2 Comments   
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...
"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...
