I have a FIXED IP, but my dhcp keeps asking for an IP and causes my Comodo Firewall to log these events every few seconds. Thus in a session, several hundred events are logged. This has no effect on my system, but seems unnecessary work for the Firewall. How do I disable the dhcp in my Windows XP to stop these requests and how do I enable this feature later if needed ?
Fixed IP, meaning static ip, for your wan? You can have the following Router IP > internal to router, normally 192.168.x.1 Wan IP > external to the web, ie. 216.211.120.131 Lan IP > per machine, so it might be 192.168.x.2 Dhcp on most routers is set to start at 100, so in this case your Lan IP might be 192.168.x.100 Dhcp is an option in routers, that can be turned off if you use static ip's in your local network. Dhcp is an option for your NIC, and you don't really turn it off when you set a static IP. You turn it off by shutting the service down to disabled instead of manual or automatic. If you use static Ip in your house, turn Dhcp service off, set your Ip on your nic, and possibly stop the router from serving dhcp. This should have no bearing on whether or not your Wan IP is static or assigned, as this is all internal stuff to your Lan. Sul.
If you want to prevent frequent DHCP renew/rebind, you can do one of the following: 1) Login to the router, for the LAN interface add static IP for your PC mac. Then in windows, add the static IP. 2) Login to the router , for the LAN interface increase the lease time to a very high value or infinity. Windows will still use DHCP but now less frequently.
