Windows XP SP2 Concurrent TCP Limitation (FIX)


Recommended Posts

Spent the night looking for this info myself. Though I'd pass it on incase anyone else is looking for it.

Seems with SP2 Microsoft decided they would limit the concurrent TCP connections to 10. Means for anyone using P2P or anyone trying to iniate alot of connections for whatever reason will be limited in their speeds.

Heres the fix.

**EDIT YOUR FILES AT YOUR OWN RISK. I NOR MSFN TAKES ANY RESPONSIBILITY IF YOU SCREW YOUR NETWORK STACK**

With that said it does work and is running currently on my machine.

The file we need to edit is C:\Windows\System32\drivers\tcpip.sys

This file should be exactly 359,040 bytes

1. Open it up in your in your Hex Editor.

2. Goto Offset 130 (Hex) or 304 (Decimal)

3. Replace these 4 bytes 6E 12 06 00 with these 4 bytes 62 13 06 00

4. Goto Offset 4F322 (Hex) or 324386 (Decimal) (make sure its from the beginning of the file not your previous place)

5. Replace these 4 bytes 0A 00 00 00 with these 4 bytes FE FF FF 00

Save and ignore any WFP error messages you may recieve.

This will remove all limitations. So be warned if you are a click happy person and you do get infected with a worm its sure as hell going to spread pretty quick.

I"m just curious......

have you not been to the board lately?

In most release scenes, this would be a "dupe"

Look in the Windows XP forum, under "Needed Hack FIles". THere is a website linked with this info, ALONG with a program to patch it for you.

I apologize.

But yes your spot on. I don't stop by very often and when I do I certainly dont have time to check every forum. I only stick around in the Unattended.

Sorry.

It's all good. I typically stay around here too :P lol
