Did you try the patches I suggested above for SP2? Some people find one or the other is better.

Oh ... something else about SP2, it resets the firewall back to default. You'll need to get into the control panel & recheck the settings. That might be a big part of your problem. Not to mention the less allowable simultaneous connections. The patches will increase those. Check them out.

Tried the patches,exception is still checked but nothing.I'd be willing to bet that, the people who have Gnuc working currently,the majority, have'nt done a complete reinstall for at least 6-8 months.Because,I have'nt done anything different to what I have done in the past when re-installing, except before it worked without a hitch.Particularly on two diff machines in my household!

Did you try the nodes I posted?

Sorry,but I'm not that familiar with connecting to nodes or ultra peer etc,but when I reinstalled again & again I took notice of what I installed each time.After installing all the basic drivers etc(chipset,ethernet)bare minimum.Gnucleus 2020 worked better than ever.As soon as I installed sp2 it started timing out.Back to bare min again it worked perfect but as soon as I installed ATI drivers(which forces u to install .net 1 or else)(maybe time to change back to Nvidia) it started timing out again.
Like an equation when 2&2=5, it is easy to see what might be causing it, but difficult to find the answer!

Just curious whether any of the members that have a fair bit of expreience configuring Gnutella,have done a full reinstall of Windows from scratch in the last few months.Due to hardware problems etc,I have done at least 3-4 reinstalls since Aug last year.Each time I have repeated basically the same install sequence each time,but the last two times something is different.The fact that Gnucleus works perfect on SP1 but on installation of sp2 it immediately stops working proves that MS is behind it.I still keep seeing posts where Gnutella has stopped working after reinstallation but no one seems to point the finger in that direction?
