Pinging the guest required before UDP communications will work

I have Windows XP Mode set as a guest under VMWare Player 3.1.4.  The host is Windows 7 x64.  The guest's network adapter is set as bridge mode but not replicating network connection state (although I tried that also).  I have a program that communicates with a host program using UDP over two ports.  The programs will only begin communicating after I ping the guest from the host.  Until then, they just hang waiting I suppose for the comm link to work.  I have firewall rules set up, but I'm pretty sure the same problem existed with the firewalls disabled.  Has anyone experienced anything like that?

I read this thread:

Very slow network throughput Host->Guest but not Guest<-Hosthttp://communities.vmware.com/thread/34497

and turned off TCP Segment OffLoading as mentioned.

Seems to be OK now.
