After installing Windows Live OneCare on my new laptop, I wanted to set a partership with my mobile device to no good, Vista's Mobile Device Center wouldn't "see" my mobile phone. A little digging got me to this article:

Frankly, it is a little bit surprising that OneCare would not recognize mobile device thru the Mobile Device Center.
 Follow these steps to allow Windows Live OneCare to recognize Windows Mobile Device Center: |
 | |
 |
| 1. Open the Windows Live OneCare application by double clicking on the system tray icon

|
|
2. On the left pane, click on Change OneCare Settings and accept prompts to bring up settings screen

|
|
3. Navigate to the Firewall tab and click on Firewall Connection Tool

|
|
4. Ensure that ActiveSync/Windows Mobile Device Center – synchronize my mobile devices with my computer rule is checked

Click OK to exit the tool. |
|
5. Click on the Advanced Settings button to bring up the advanced settings configuration screen

|
|
6. Navigate to the Ports and Protocols tab and click Add

|
|
7. Make sure to:
- Create a port called “Windows Mobile Device Center”
- Specify TCP Port range to be port 5721
- Specify “Inbound [local ports]” in the “For Connections” dropdown
- Scope is set to “Local network (subnet)”

Click OK to exit the screen and successively to exit all Windows Live OneCare screens. |  | |
