You may need to re-instal al the software on the pocket pc. You should have had a disc supplied with it.or it maybe this. When I set my pocket pc up I had this problem because I said to zone alarm not to allow active sync to access the internet. Have you added any fire wall software which might be blocking the connection.
The top option on my ipaq for cradle use is usb selected from drop down list. The lower option for remote synchronizing is selectable only as default. If you then click ok. the next screen has a greyed out sync and stop button if you tap the sync button you will get into the connection settings. if it's the same as mine. Hope this helps
i had trouble with my toshiba pocket pc and resolved it by the following:
1. Click on start (top left) 2. Click on Active Sync 3. Click on tools (bottom left) 4. Click on options on the pop up menu 5. Tick 'Enable synchronisation when cradled using USB' 6. Tick 'Include PC when synchronizing remotely and connect to ....... 7. Click OK
Remember not to turn your Medion PPC on when putting in the cradle, it must be turned off.
The latest version of Active Sync is 3.7.1 and can be found at click here
