Host only network in vmware only works in one direction

I have the following setup, Windows 7 Host, Windows XP Guest

Windows XP Guest Bridged adapter 1 
Adapter 1: Bridged 
IP 10.1.1.55 
Subnet 255.255.255.0 
Gateway 10.1.0.1 
DNS 10.0.0.201 10.0.0.205 

This adapter works correctly and gives me internet access

I have added a second private host only adapter on the guest

Windows XP host only Guest 
Adapter 2 Adapter2: host only 
IP 192.168.50.2 
Subnet 255.255.255.0 
Gateway DNS 

On the Windows 7 host I have

Windows 7 Host Only Adapter (Vmnet1) 
IP 192.168.50.1 
Subnet 255.255.255.0 
Gateway DNS 

From the XP Guest VM I can ping both 50.1 and 50.2 no problems.

From the Windows 7 host I can ping my own 50.1 IP address but 50.2 times out.

Here is my virtual network editor screenshot showing the correct subnet, I have VMNet1 as the host-only adapter and DHCP turned off.

Why can I not ping 192.168.50.2 from the Windows 7 host?

I have tried disabling the firewall on both PCs, I have also tried restarting both the host and the guest.
