I just got SP2

[AngelicKnight]

Hmm...Well, I'm running SP2 on my home computer and haven't had any problems with it, though I don't do any port scanning from that machine. And I installed in right after it came out for testing (I know, probably not the brightest idea in the world). So far, so good!

<edit> Correction, I have had one problem -- CD-RW drive stopped working and computer locks up when I run Ahead Nero...I'm thinking a corrupted driver maybe? I don't think it has anything to do with SP2, but given the timing I guess it's a possibility...hmm...I'll have to research that.

pooh sun tzu &gt; The patch that you suggest merely changes the maximum limit of outbound uncompleted tcp connections. It does not remove this limit, only changes it. While I can believe the code is free from spyware and malware, I would still have a very hard time getting myself to install and run 3rd party unsigned code on any of my production servers, at home or work.

However, since I have free time and test beds to experiment on, I did try the file that you posted. It appears to only modifiy winnt\system32\drivers\TCPIP.sys. By default, SP2 limits the amount of outbound connections per second to 10. The program you posted can be ran with a parameter of /L=# where # will be the new number of connections per second.

So you can use a 3rd party program written by some kid to modify a system file to hopefully prevent windows from stopping your amount of outbound traffic.


Other note as well, like I said before, this still does not 'uncap' the limit, just changes it. Even after setting it to 16,777,214 connections per second, I was still able to get event log to generate ID 4226 errors. 4226 is the new error code that is issued whenever windows reaches the set limit of outbound uncompleted tcp conncetions, and blocks further ones.

Correct. However, 1677214 WAS the limit cap for preSP2 on 2k and XP SP1. While it was called uncapped, the actual number was 1677214 because of how insanely high it is. That setting is no different than Pre SP1

Even after setting it to 16,777,214 connections per second, I was still able to get event log to generate ID 4226 errors. 4226 is the new error code that is issued whenever windows reaches the set limit of outbound uncompleted tcp conncetions, and blocks further ones.

Then you need to make sure the settings held by running it again to verify (not reset, just run) the amount of allowed connections. I don't have any errors being logged even with trillian, firefox, bittorrent (hosting sp2), and music streaming. I don't know why you are getting errors, but it isn't par and may be your settings. Like I said. Rerun the executable and see if your configuration settings held. This means run it without the /L. Windows tries to replace this file if you are not running it in safe mode, so make sure you did it in safe mode as well.

It appears to only modifiy winnt\system32\drivers\TCPIP.sys

Correct. Because that is the only file in the entire OS that controls the rates/limits on tcp/ip connections. There wouldn't be a reason to modify anything else since nothing else touches it.

So you can use a 3rd party program written by some kid

Careful there. You trust nmap don't you? And that wasn't started by a 31337 company.

I have 3 computers I have to connect a keyboard/mouse/monitor up to do
the SP update.... It does lock down the firewall so the non-MS software I use to
admin these computer will break until I add the firewall rule in manually...

But so far I have had no major glitches in in my other updaes so far other
than it takes 1-2 hrs for a computer to run its full course in updating XP
To bad MS canot make an update that takes longer to install tan the orginal
install of XP

Does anyone have the link for a list of the software affected by sp2?

AngelicKnight: Yes, there is a compatibility issue with Nero. I installed Nero Express 6.x after updating XP and it actually pulled up and told me that there was an issue with SP2. You can get a patch from http://www.nero.com/us/updates.html which fixes that up.
