Hi,

I'm currently working with a host of handhelds for part of a pilot project. Most of the units are running Windows Mobile 2003/Activesync 3.8.

Up until recently i haven't had a problem with the devices connecting to the internet while docked, as the proxy server was automatically being detected.

However, i have now started to use new devices running WM 5.0. I have had to upgrade Activesync to 4.2 and now, the proxy settings are not being detected. I can manually configure them, which works fine, but as these device will be given to others for testing this is giong to be a problem. (3rd party software uses internet for data transfer).

Has anybody got and ideas how this can be altered?

Cheers.

Welcome to Geekzone... Just to clear my head around this, are you talking about the ActiveSync passthrough service, or are you talking about a proxy server on your network?

It's the proxy server on our network. Though when the device gets given to the user he will be using is on another network. This could be another private business network or thier own home network.

Ok... So the device was doing a proxy auto discovery with previous versions, but with Windows Mobile 5.0 it is not?

I don't have a proxy here, but I can ask a friend to test somewhere else, that's why I need to understand the exact nature of the problem.

Also, as ActiveSync 4.x uses a different approach to connecting the device (via NDIS instead of a serial connection), have you checked if a personal firewall (if any, including the built-in Windows Firewall) is configured to allow ActiveSync to communicate over IP?

In response to your first question;

Yep, i had no need to carry out any manual configuration of windows 2003 devices (I was running Activesync 3.8) and they were running through the company's proxy server. I checked the settings on these devices and the information was automatically entered correctly.

Secondly;

There is no 3rd party firewall on my pc and the Windows Firewall is off as part of the company's standard build.

Thanks... Last question then, before I go off looking for more on this: where did you check the Proxy settings on Windows Mobile 2003? A connection in Connection Manager?

Yep, under the 'connections' heading. -- 'Edit my proxy server'. The information is in there.

Got some information back from Microsoft on this. In summary with the release of ActiveSync 4.2 it is expected that the proxy settings will be transfered to the device when ActiveSync is set to Automatic under the Connection Settings "This computer is connected to:'.

Apparently this is a change from ActiveSync 4.1 where this is expected to be trasnfered if it is set to Automatic or Work Network.

So check your ActiveSync configuration on the desktop. If it's set to Internet then proxy settings will not be transferred.
