I have following setup: a windows server 2003 dedicated server with tho nics. One is connected to internet (no modem/router), and second one is connected to private network. Server has DHCP server installed on it and internet nic is being shared for internet access.
The problem is sometimes server loses connection to the internet, so same happens to private network. So far I can manually fix it by releasing and renewing IP address.
What could be the cause of this problem? DHCP lease from ISP?
Thanks
This is probably an intermittant router/modem fault, but you have to check your side of things through doing some swap-and-tell :-)
Swap cables/network/patch ports and as a last resort, swap the interface function on your windows server, to see if the fault is tied to a driver or NIC.
