I'm experiencing a very frustrating sync problem with my Toshiba e570 running PPC 2002. I doubt it?s unique to the Toshiba, however, because I have seen the same problem described on another board by at least two others with different devices ? one an iPAQ 3765, the other a Cassiopeia EM-500 (no solution to the problem has been posted on the other board). I sync my e570 to my desktop PCs at both work and at home. I have been doing this without incident for over a month, but I have recently received this message on both PCs every time I attempt to sync: "Synchronization cannot be completed successfully. Disconnect your device and try again. If the problem persists, see the Microsoft ActiveSync Troubleshooter in Microsoft ActiveSync Help on your desktop computer." I have WinXP on both machines, and have installed every XP update. At first I thought this might be the issue, until one of the other two people said he was running PPC (not 2002) with Windows 2000 on one machine, and Windows 98 2nd Ed. on the other. As I?m sure many of you have noticed, there is no functional ?ActiveSync Troubleshooter,? so that was a useless avenue. I've uninstalled and reinstalled ActiveSync on each machine (including removing registry entries according to MS instructions), and I am still unable to sync on either. I've tried re-establishing partnerships using only one partnership and even renamed by device and still no luck. I called Toshiba tech support who spent a great deal of time with me to no good result (very helpful and cordial, by the way, just unable to solve this problem). Any advice is certainly appreciated. Thanks.
