Access denied from LAN device (no replies)

MySQL server is on desktop running Windows 7. IP4: 192.168.1.2 port 3306
laptop is running Vista ip4: 192.168.1.5
Both are running Workbench.

On the desktop Workbench I created a user 'usrname' for host 192.168.1.5
I also set a Windows Firewall rule to open port 3306 to LAN devices

Trying to use the laptop Workbench to access the desktop server, I get "Access Denied for user 'usrname'@'pc-name'

I can access the desktop Apache server to run MySQL applications, but I want to be able to access MySQL directly.

Any suggestions ?
