Here is some documentation from Microsoft site.
It looks like they may be aware of more problems than
this addresses. I did a Google for pda sync problems and
found that the issue seems to be more of a microsoft problem
than a Dell Axim problem. It appears that it is quite widespread
so maybe they will come up with some fixes quicker than if it
was a rare problem.

ActiveSync 4.0/4.1 USB Connection Troubleshooting Guide
In some specific cases, Windows Mobile device connectivity to a Windows PC running Microsoft ActiveSync 4.0 may experience connection problems. This document will describe the known issues, and how you can resolve them.
*Please note that ActiveSync 4.1 is now available and you should upgrade to ActiveSync 4.1 for devices running Windows Mobile 5.0 software. In some cases, issues in this document will be resolved by upgrading to ActiveSync 4.1. However, the contents in this troubleshooting guide also apply to ActiveSync 4.1 in many cases. It is recommended that you reference this guide for issues hit with ActiveSync 4.1 as well.
Issues:
The symptoms of USB connection problems between a Windows Mobile-based device and ActiveSync 4.0 may include any of the following:
*
Connection between a Device and PC is dropped during data transfer or synchronization.
*
Connection is never established between PC and the Device and there is no visual feedback.
*
Synchronization is completed partially, but does not finish as intended.
*
Windows appears to stall or crashes upon connecting a device
Cause:
Most cases of ActiveSync 4.0 USB connection problems as listed above are caused by Windows desktop firewall applications or applications that manipulate network traffic. These applications conflict with the TCP traffic between your device and the PC, causing data transfer and connection issues. The list below provides some known applications that may cause problems connecting your device to your PC.
Desktop Firewall Applications
Firewall applications are designed to block network traffic and secure the desktop PC from incoming network connections. Since ActiveSync utilizes TCP ports for data transfer with Windows Mobile devices, you may need to explicitly allow this traffic to be un-blocked by Firewall applications. To do so, you must add ActiveSync application processes into the Firewall Programs Exception List.

For additional firewall software not mentioned, please consult your firewall application documentation on how to add ActiveSync application to the exception list.
Note: ActiveSync files include:
*
Wcesmgr.exe
*
Wcescomm.exe
*
Rapimgr.exe
These application processes are located in the ActiveSync installation folder (C:\Program Files\Microsoft ActiveSync\ if installed in C drive with default settings).
ActiveSync also uses the following ports for communication to/from these processes:
Inbound TCP:
*
990
*
999
*
5678
*
5721
*
26675
Outbound UDP:
*
5679
Network Connection Managers
Network Connection Managers are utilities that intelligently manage connection interfaces so that a PC with multiple connection methods (e.g. Ethernet, Wireless LAN, etc.) can leverage the best connection. In some cases, the utilities will shut down network interfaces and promote other interfaces for the best connection performance. Some of these utilities are implemented as NDIS Intermediate Drivers that monitor and affect the Windows system TCP/IP stack.
Since Windows Mobile 5.0 and ActiveSync 4.0 now utilize the Windows system TCP/IP stack for communication, the device connection will appear as a network interface and can be interrupted by a Network Connection Manager utility. Some utilities may mistake the ActiveSync connection as a valid internet connection and shut it down in favor of Wireless LAN connection.
If you experience issues with device to PC connectivity, please upgrade to ActiveSync 4.1.
VPN Clients
Virtual Private Network (VPN) Clients are utilities that facilitate a remotely connected PC to authenticate and join a secure private network. Some components of VPN clients are implemented as NDIS Intermediate Drivers that monitor and affect the Windows system TCP/IP stack traffic.
Since Windows Mobile 5.0 and ActiveSync 4.0 now utilize the Windows system TCP/IP stack for communication, the device connection will appear as a network interface and information between the PC and your device may be erroneously interrupted by VPN Clients. This may cause difficulties in connecting the device with a PC while the PC is joined on a Virtual Private Network.
If you experience issues with device to PC connectivity in this case, please upgrade to ActiveSync 4.1.
Parental Control Utilities
Parental control utilities are often designed to block network traffic to designated internet addresses. These utilities may be implemented as a Layer Service Provider that monitors network traffic across multiple Windows applications. ActiveSync communications between the PC and your device may be erroneously interrupted as well by these Layer Service Providers making it difficult to establish a connection.
If you experience issues with device to PC connectivity, please upgrade to ActiveSync 4.1.
Hubs & Docking Stations
USB hubs and laptop docking stations have not exhibited consistent stability with Windows Mobile devices and ActiveSync.
Please connect the device directly to the PC USB ports if you experience connection drops or inability to connect through a USB hub or docking station.
Network Traffic Optimizers
Network Traffic Optimizers are utilities that enhance a connection to increase connection throughput. In some cases, this is done by modifying the network packets or re-directing network traffic to save transfer time. Some of these utilities are implemented as Transport Driver Interface Drivers that are installed in the Windows system to monitor the TCP/IP stack.
Since Windows Mobile 5.0 and ActiveSync 4.0 now utilize the Windows system TCP/IP stack for communication, the device connection will appear as a network interface and information between the PC and your device may be erroneously interrupted by Network Traffic Optimizers.
If you experience issues with device to PC connectivity, please make sure that a Network Traffic Optimizer is not conflicting with the connection. You can check this by disabling or uninstalling the Network Traffic Optimizing software you are running.
Synchronization Issues with Microsoft Outlook
If you are experiencing difficulties setting up and completing synchronization of data with Microsoft Outlook, please refer to the following section to find details about symptoms and workarounds.
Synchronization Error 85010017
In some cases, ActiveSync will fail to synchronize data with Microsoft Outlook with Synchronization Error code 85010017. This could be due to the presence of large volume of items on first sync or specific large items such as a calendar item with many meeting attendees. Some targeted instances of this have been fixed in ActiveSync 4.1.
If you are experiencing this on Windows 2000 or Windows XP SP1, please upgrade to ActiveSync 4.1. Otherwise you can try archiving your inbox to reduce the number of items in the mailbox for synchronization.
Synchronization Error 85010014
ActiveSync reports a Synchronization Error code 85010014 because of one of the following reasons:
*
Synchronization Fails because Application Data Folder is Redirected
*
Synchronization Fails because Outlook is in Offline Mode
*
Synchronization Fails because of Outlook script blocking
*
Synchronization Fails because ActiveSync is incorrectly registered with Outlook
Application Data Folder Redirected:
If your Application Data folder under Documents & Settings folder is redirected to an external source, you will experience synchronization failures.
Please upgrade to ActiveSync 4.1 if you are experiencing this issue.
Outlook is in Offline Mode:
If you are attempting to set up synchronization or are synchronizing when Microsoft Outlook is in Offline mode or when you do not have connectivity to the Microsoft Exchange Server with Outlook, you may experience synchronization failures.
Please upgrade to ActiveSync 4.1 if you are experiencing these issues.
It is still recommended that you have Microsoft Outlook in the Online mode when synchronizing with your device.
Outlook Scripting Blocked:
Certain Desktop PC security applications may disable Outlook scripting which is required for ActiveSync too set up communications with Outlook to synchronize data.
Please ensure that script blocking for Outlook is not enabled to work around this issue. Please consult your PC security application documentation on how to disable script blocking for Microsoft Outlook.
Incorrect Outlook Registration:
Please see “Outlook needs to be Re-Installed or Repaired” section for details.
Device Synchronization App Crashes or sync fails
We have found that certain data items, when synchronized with the device could cause bad properties to be set on the Windows Mobile device.
If you are experiencing frequent sync failures or device crash errors, please upgrade to ActiveSync 4.1.
Outlook needs to be Re-installed or Repaired
In some cases when Microsoft Outlook is not the primary Email client on the PC, you may see the following symptoms:
*
Synchronization Error 85010014
*
Error that Outlook is not installed, even though it is
Please upgrade to ActiveSync 4.1 if you are experiencing these issues.
