This is a security feature of XP (SP2 onwards), and a pretty useless one at that. You need to edit the tcpip.sys file.Windws XP SP2 introduces a few new twists to TCP/IP in order to babysit users and 'reduce the threat' of worms spreading fast without control. In one such attempt, the devs seem to have limited the number of possible TCP connection attempts per second to 10 (from unlimited in SP1).
This argumentative feature can possibly affect server and P2P programs that need to open many outbound connections at the same time.provides an automatic (and manual method if you're worried about the Event ID 4226 Patcher application) for editing the tcpip.sys file. I used the automated (application) many years ago and it worked like a charm.

I know, I know, this very obsolete stuff, but. I would like to know if there is any way to get NetBEUI running under XP SP3.I have a small Workgroup that still has some W2K machines running NetBEUI for file sharing within the LAN. (TCP/IP file sharing is turned off; I was advosed long ago that it was safer this way because of various Microsoft vulnerabilities in NetBIOSover Tcpip.) I have two XP XP3 machines on this Workgroup that were upgraded from SP2 AFTER NetBEUI had already been installed, and they are networking just fine.Here's the problem: I am now upgrading one of the W2K machines with a XP SP3 new-install CD - there is no way to uninstall SP3 and re-install it after NetBEUI.
(Interestingly, NetBEUI still appears in the VALUEADD directory onthis CD, suggesting that it might work.) I have notes from the days of upgrading the other XP machines from SP2, however, that it was necessary to install NetBEUI (the W2K version was recommended because of compaitbility issues with the W2K machines)BEFORE installing SP3, but I don't remember why.Can anybody offer a solution (preferably not involving reconfiguring my entire Workgroup)? OK, so I tried installing the (older W2K version, as explained above, of the) NetBEUI protocol and UNbinding TCP/IP from File and Printer Sharing and from Client for Microsoft Networks on the LAN on my new native SP3 XP machine, as I had done for the others.I rebooted, and the unbinding settings were still intact this time. (My old notes indicated that these settings would revert to the original, everything bound, configuration after a reboot if and only if NetBEUI was installed AFTER the SP3 upgrade.)I haven't tried connecting to the LAN throught NetBEUI from this machine yet - several other steps to perform first.
