I have had the same problem syncing my C3100 & MS Outlook:
I initially bought a the 6000L. This was damaged and I duly bought a second hand C860 and installed Cacko. I could use the 6000L Intellisync software to sync with the C860 - no problem. (If any C860 owners are interested they can download it here: http://www.ingogo.net/6000Lpcsoft.zip
Unfortunately my C860 started playing up after I upgraded to Cacko 1.23. I then found 3 badblocks in the flash memory. #$%&!!!. Seems to be a common problem looking at some of the other posts. I then upgraded to a C3100 from Conics. (Great service BTW)
I could connect to the C3100 using the NDIS driver ie I could ping my zaurus from the pc and the other way round. I could not get Intellisync to work: it would do exactly what you have described: the syncing would seems to start ok and then bomb out saying I should reconnect the zaurus. I tried various combinations of USB I/O & USB TCP/IP with no luck.
I followed the instuctions from http://www.trisoft.de/download/c3000sync.zip
more or less:
1) I made a copy of the original "C:\Program Files\Sharp Zaurus 2\Intellisync for Zaurus" folder - still there from the original 6000L English software.
2) Uninstalled Intellisync for Zaurus, restart Win XP
3) Installed Japanese software as explained in the trisoft document + reinstalled zaurus NDIS driver + restart Win XP (important part of the Windows experience)
4) Copied "Intellisync for Zaurus" over the Japanese version
MS Outlook 2003 sync now works flawlessly. The only thing missing now is "Backup & restore"
Hopes this helps.

Need some help here. I have done everything in this thread to sync my XP SP2 laptop with my C3100. I installed the japanese and paste the english over (as posted by Trisoft), didnt work, then installed only the japanese, didnt work either. I get the LAN connection up, my laptop connection gets the IP address from the zaurus (defaul setting), but when syncing, it states an error that says that it can not connect, that I should try to unplug, then re-plug and try again 30 sec later.
