I just got a x51v and have a dell d600 laptop.

At work I have a docking station and have the cradle connected to the docking station usb port. Installed activesync 4.1 and all is working fine.

Brought the cradle home this evening and plugged it into the back of of the laptop. But activesync now will not connect. It gets hung connecting. Went through the whole uninstall and reinstall active synch, soft and then hard resets of the pda (luckily I dont have much data yet). But no go.

Looking on the web I found a pda help site that says often there are sync problems unless one uses the same usb port as where the pda was installed.
I followed his suggested procedure of going into device manager and uninstalling the PPC usb driver. But still no joy.

Anyone know what might be the problem here? Thanks for any help.

Continued searching and found some info on this aximsite archive.
Windows XP firewall.

Turned it off and now the pda will connect.

I posted this in another thread so maybe you've found it already, but if not it's worth a go....

(my) problem solved

--------------------------------------------------------------------------------

Setup
-------
Windows XP, Dell x51v, ActiveSync 4.1.0 (Build 4841). Only Windows Firewall installed. Axim connected to HP laptop in a docking station and via a USB hub

Problem
----------
Having spent several days attempting to sync my x51v and not even being able to get it to connect to ActiveSync via USB I stumbled across a post (http://www.geekzone.co.nz/forums.asp...8&TopicId=5741) that pointed me to the DHCP client. Having confirmed that this was running (via Services) I looked at the properties for the 'Local Area Connections 6' that was associated with 'Windows Mobile-based device #4' via Start -> Settings -> Network Connections (as you can probably tell, have attempted a number of re-installs!)

Looking at the Properties revealed that TCP/IP was not even enabled for this network connection! I enabled it and sudddenly both laptop and PDA sprang into life. Have now synch'd and everything is good with the world again.

Having raised a call with Dell I have informed them of the fix (or at least sent them an e-mail via their auto-responding e-mail address). Hopefully they'll update their on-line trouble shooter as I can't belive I'm the only one with this specific problem. May also send Microsoft an e-mail as their troubleshooting guide doesn't mention this issue.

Hope this post helps someone else out there who has been suffering the same pain as me!
