Hi,
The issue is the following when i'm working on XP client the NAP works correctly, but when i try with a Windows 7 client, as i add the client on the domain and the nap group policy is applied on it the client cannot ping the loopback adress but it can ping
the DC, the NPS and the XP clients, BUT the DC, NPS and all the hosts cannot ping my windows 7 client, at first i thought that the problem came from the firewall or the antivirus but it's seems not because i've tried disabling them but noting changed.
Finally when i stopped the nap service on the client the client starts to ping itself and the others could ping my 7 client.
even when i look in the routing table of the client everything looks OK
PS:i'm working in a Vmware envirronnement
Best regards
