SP2 and TCP/IP connection limitation

[Agozer]

I just upgraded to Service Pack 2 a few days ago because Microsoft is dropping the support for SP1. I don't have any problems with SP2, but I've been reading about TCP/IP limiting the number of open connections to 10 or somesuch. Now, what exactly does this do? I also read that there is a fix for this issue somewhere.

 

Like I said, I haven't had too many problems with BitTorrent or connections in genetal, although web-browsing seems a little slow at times. So, has someone else used this "fix" to fix whatever limitations SP2 brough about and by doing that, did the fix improve downloads/uploads at al?

 

Also, does someone have any links to this fix?

Well, if all your upload speed is in use by say a BT client, web browsing will be slow regardless.....as your communication with the web server for GET and other requests are slowed.

Anyway, the limitation is best to fix when you're a P2P user, as it's not the actual "connections" that are limited, but concurrent half open connections. That being connections in progress etc. If more than 10, others will be ignored.

 

I have the fix here.

 

Just make sure after changing, you hit Cancel on the Windows File Protection thing that pops up, or Windows will replace it.

Well, my BitDefender virus scanner promptly stopped me after I opened the folder where I extracted the contents and explained that the exe files is infected with Backdoor/Virkel.A

 

I don't know if this is a false positive or an actual trojan. Comments?

 

EDIT: I found out that the latest BitComet client can also patch TCPIP.SYS to allow more half open connections. Thanks anyway.

Definitely a false positive. My Norton Antivirus is up to date.

I would imagine due to what it does, it could be mistaken.
