SP2 -> can't communicate

[Yippee38]

I had to upgrade my work PC to WinXP SP2 - no choice here - and now I cannot sync to Qtopia Desktop at all.  I have disabled all of the WinXP firewall functions, and even added all of the Zaurus application as "allowed" applications in the firewall (even though the firewall is disabled).  I can ping my 5500, but none of the applications will communicate.  When I try to FTP or synch to Qtopia, I get the sync screen on the Z, but it won't connect.

When I connect it to my home PC with WinXP (pre-SP2) it works fine.  I'm using the same settings on both PC on both sides.

FWIW, I'm using the USB - TCP/IP (advanced) settings with the same IP address in both the Z and the Zaurus Manager software (the default IP).  I've got the 3.10 Sharp ROM and the latest desktop software from the Sharp site (fresh re-install).

Does anybody have any suggestions on what I can try to get my communications back?

FWIW I have similar probs on two XP systems but with Outlook instead.

The SP2 system will only not communicate other than by pinging it via Windows CLI.

The SP1 system will ping and will allow me to browse the Zaurus file system but Intellisync won't communicate with Outlook nor will it allow me to send files to the Zaurus (although I can transfer them using Windows Explorer).

I've tried all the usual things of uninstalling, re-installing blah blah blah. It seems broken to me and that nothing other than a fresh install of Windows might possibly get it going.... and I'm not prepared to do that atm.

I've not had any response to my pleas for help so, I guess nobody can suggest anything new.
