Anybody having problems with Windows XP SP2 connections?

I think this is a result of an overloaded network, but we are seeing
connections dropped, and an error 4226 in the event log. This has been
traced to:-

Limited number of simultaneous incomplete outbound TCP connection
attempts on the page
http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2netwk.mspx#EIAA

Anybody got any ideas what could be causing this - or is it Microsoft's
latest attempt to restrict access to Windows machines ;)
