I've been having some fun and games this evening trying to get my Windows Mobile 5 smartphone to connect to Windows Mobile Device Center (the new name for ActiveSync) on Windows Vista but I've finally got it working and here's the secret. You just have to open up the following ports in your Firewall program:
- TCP 990
- TCP 999
- TCP 5678
- UDP 5679
- TCP 5721
- TCP 26675
Have fun!!
