Dear All,
I implemented DHCP-NAP-Enforcement in my Environment and it is working perfectly.but i have a problem is that when Compliant Computers access the network and then goes into sleep mode, when they wakeup i see that they are assigned the full mask 255.255.255.255 and I have to restart the NAP Service to obtain the Default Mask, Checked event viewer and i found this error happens during this scenario
An error occurred when DHPQEC tried to renew DHCP lease in the adapter {9b5cb0da-2416-40b1-bcfa-1f95a8389c15}. Error code is 0x79
