I wrote about this about two weeks ago, but the problem seemed resolve itself, so I went no further. Now, the issue has arisen again. When I got home last night I docked my X51V and it synched okay with my home computer. Later, I was having some issues with my Spb Pocket Plus so I uninstalled it and then reinstalled. After that I couldn't get my Axim to synch with the desktop. I went to bed and tried in the a.m.. but still no luck. When I got the office this a.m. the same thing happened on my work pc. - no synch. When I left work last evening the synching was working fine. At work I uninstalled MS activeSync 4.2 and reinstalled it, but still no synch. I have tried multiple soft resets without success. Does anyone have any suggestions or thoughts short of a hard reset, ugh?

try disabling all today plugins and synching again, deleting the partnership on both axim and pc (though you lose synced email this way) and repartnering, unticking the 'advanced network functionality' box in the usb section of the connections setting window, or using the 'detect and repair' in ourlook. those solutions work for me from time to time. Stupid activesync.....

All of a sudden I was having problems with AS 4.2 where my computer was saying it could not recognize the device. I ended up loading the new AS4.5 beta and it said the same. Then I did the soft reset and it started working. If you haven't tried a SR you might see if that did the trick. Do you have a firewall that may be causing a conflict?

See my post to "51v Can't sync - I've hard reset, soft reset, uninstalled, reinstalled! Help! below." What worked for me was dealing with the personal firewall from McAfee. Once I changed the parameters to all ActiveSync in as indicated in the Microsoft website for Windows Mobile, I synched immediately.
