| Description | Description a (Error): The DNS proxy agent was unable to bind to the IP address <ip address>. This error may indicate a problem with TCP/IP networking. The data is the error code. Data: 0000: 1d 27 00 00. Description b (Warning): The DHCP allocator detected network address translation (NAT) enabled on the interface with index <number>. The allocator has disabled itself on the interface in order to avoid confusing DHCP clients. |
| Event Information | Resolution steps for Description a (Error): CAUSE: The ICS service is one implementation of Network Address Translation (NAT) that Windows 2000 uses. The ICS service automatically sets up a mini DHCP scope and a DNS Proxy service to enable clients on the private network to use ICS and get on the Internet. <p>The DHCP allocator and DNS Proxy services are not configurable in ICS and start as soon as the service is enabled. Because these services bind to the same TCP ports that a DDNS or DHCP server uses, ICS conflicts if these services are running. RESOLUTION: To resolve this issue, do not run the ICS service on a DHCP or DDNS server. NAT (which is installed using routing protocols in the Routing and Remote Access Service (RRAS) snap-in) works correctly if you do not enable the DNS Proxy service or the DHCP allocator.</p> <p>To setup NAT to NOT use the DHCP allocator, do not check the box for "Automatically assign IP addresss using DHCP" on the Address Assignment tab of NAT properties.</p> <p>To setup NAT to NOT use the DNS Proxy Service, do not check the box for "Clients using Domain Naming System (DNS)" on the Name Resolution tab of NAT properties. Resolution steps for Description b (Warning): This issue can occur if the NAT service logging level is set to log errors and warnings. The message in the above section is a warning that states that the Dynamic Host Configuration Protocol (DHCP) allocator service is not binding to the public interface. This behavior is by design. |
