Hi,
I recently reinstalled WM2005 and found that my experience from last time didn't help to get ActiveSync 4 working with WM2005:
In 2005 the primary connection mode between devices and desktop pc's via USB has changed from a serial over USB connection (WM2002 & 2003) to a TCP/IP based connection.
This connection is made by the RNDIS (Remote NDIS) driver. On the desktop PC, you device will no longer show as a serial USB device but as a network board. You can check this by looking at the network connections.
So when trying to troubleshoot ActiveSync problems you should pay special attention to everything that could interfere with TCP/IP. I had problems when the MS ISA Server Firewall client was activated. After deactivating (and some hours of research) it finally worked, so try to deactivate personal firewalls and things like that.
Checklist:
- Does you device appear in the Device Manager as "Windows Mobile based device"?
- Does it appear in network connections?
- run ipconfig and see if it has an IP adress assigned? (should be something like 169.254.2.2)
- open network cards on your mobile device >> Settings >> Connections >> Network cards >> Click "Remote NDIS host" and see if an IP address is auto-assigned (leave the setting just look at the IP address
- if you can ping your device from your desktop PC, ActiveSync should work, too.
It turned out that the problem was that I had disabled the "DHCP Client" service on my W2k machine. The RNDIS mechanism works in a way that the CE devices act as a DHCP server. When there is no DHCP client request from the PC, it simply doesn't work (a static IP address on the PC doesn't help).
I've read a lot of posts from people claiming that it only worked after a reinstall of the OS. Since the DHCP Client service is enabled by default, this might explain why the reinstall solved the problem. So before reinstalling your OS, you may want to try to start the DHCP client service....
Hope this will help some of you..
