Too many TCP connections

 11:52 pm on Jan 4, 2007 (gmt 0)

I'm running Windows XP Pro, and our Internet has slowed to a CRAWL. Our ISP tells us it's because we have too many open connections. A look at netstat confirms that both computers on the network have probably 30+ connections each.

How do I close these? I had the computer shut down all night, but no luck. Any help is appreciated!

30+ connections is *nothing*

your problem is running on xp pro. there is a builtin limitation on the number of connections. move to windows server 2003 to fix it.

I'm also running XP Pro on most of the machines on my LAN. Most of them have around 30 connections open BUT, these are not ports open to the Internet.

If your ISP is telling you you have lots of open connections then I have to ask why?

Are you running applications which require lots of ports open to the 'net?
If not, then here's two suggestions:

- check for spyware and adware
- if your'e connected to the 'net with a cable modem or ADSL modem then replace it with a proper router.

whoops! it appears that i jumped the gun thinking that you were hosting on this computer. post #3 probably makes more sense in your situation.
