Hi,
I have an application running, where the clients contact a licensing server via UDP port 3047.
The Clients run on Win2000, WinXP Prof. Everything works.
Installed a Client on a Win7 box, tried to contact licensing server, no success.
With tcpdump on the Serverside I see about 50 UPD packets per Request, arriving from the WinXP machines an NO packet coming from Win7 client.
With windump on the Clients, same result: About 50 UDP-packets/Request leaving WinXP client, and not a single one leaves Win7 machine.
DNS resolving (UDP 53) on Win7 box works. Connectivity to other hosts works, Internetaccess OK.
Disabled Firewall and Anti Virus.
Is Windows 7 filtering/blocking HIGH UDP PORTS somehow? Any other ideas?
Thank You for your input.
Ryan
