To make changes to the configuration of IPv6 interfaces, use the netsh interface ipv6 set interface command.If you are unable to ping a remote destination by its IPv4 address, there might be a routing problem between your node and the destination node.Flushes and reloads the DNS client resolver cache with entries from the Hosts file.Sends Internet Control Message Protocol (ICMP) Echo or Internet Control Message Protocol for IPv6 (ICMPv6) Echo Request messages to test reachability.If a positive cache entry exists for a resolved name, the corresponding IPv6 address is used.
This step might not succeed if the default gateway is filtering all ICMP messages.To verify reachability with a local or remote destination, try the following.Netdiag is installed as part of the Windows XP and Windows Server 2003 Support Tools in the Support\Tools folder of the Windows XP or Windows Server 2003 product CD-ROM.You can use the netsh interface ip set address command to configure the address type (DHCP or manually configured), the IPv4 address, subnet mask, and default gateway.To check the current IPv4 settings for the correct address configuration (when manually configured) or an appropriate address configuration (when automatically configured), you can use the following.Right-click the connection that you want to repair, and then click Repair.
You can use the following tasks to troubleshoot problems with DNS name resolution.To make changes to the IPv4 address configuration, you can use the following.To display the current contents of the destination cache, use the netsh interface ipv6 show destinationcache command.
As an example of the former case, a firewall or Web server might be configured to allow only HyperText Transfer Protocol (HTTP) traffic and discard all other traffic destined for the Web server.In many cases, packet filtering is configured to allow specific types of traffic and discard all others, or to discard specific types of traffic and accept all others.Look for A records in the detailed display of the DNS response messages.You can also click Repair on the Support tab for the status of a network connection.The NetBIOS name cache is checked before sending WINS or broadcast name queries.If reachability using IPv4 addresses works but reachability using host names does not, then you might have a problem with host name resolution, which is typically an issue with configuration of the DNS client or problems with DNS registration.
Method 3 - All of the settings you mentioned were already set to automatic.IPsec for IPv6 policies that have been configured with the Ipsec6 tool.IPv4Address command to trace the route a packet takes to a destination and display information on packet losses for each router and link in the path.To display the current contents of the neighbor cache, use the netsh interface ipv6 show neighbors command.The display of the netsh interface ip show config command includes DNS and WINS servers per interface.
The Internet Connection Firewall for IPv6 is included with the Advanced Networking Pack for Windows XP, a free download for Windows XP with SP1.Click Start, click Control Panel, and then double-click Network Connections.Troubleshoot IPv4 communications by verifying IPv4 connectivity, verifying DNS name resolution for IPv4 addresses, verifying NetBIOS name resolution, and verifying IPv4-based TCP sessions.This file maps host names to IP addresses, and it is stored in the systemroot \System32\Drivers\Etc folder.Click Details on the Support tab to display the media access control (MAC) address, DHCP lease information, DNS servers, and WINS servers.Displays protocol statistics and information on current TCP connections.For computers running Windows Server 2003, Routing and Remote Access IPv4 packet filters on routing interfaces with the Routing and Remote Access snap-in.
This allows you to test network connectivity for specific traffic before the services are in place.Depending on the type of problem, you might do one of the following.Some common questions to ask during troubleshooting include the following.To try and isolate the components that might be at fault when approaching a troubleshooting issue, you should determine what works, what does not work, whether it has ever worked, and what has changed since it last worked.To verify that a TCP connection can be established using the known destination TCP port number, you can use the telnet.The following tools and tasks can be used to troubleshoot problems with NetBIOS name resolution.To flush the neighbor cache, use the netsh interface ipv6 delete neighbors command.The chapter includes the following pieces of key information.
For more information about Ttcp, see Testing Network Paths for Common Types of Traffic.The Network Connection Repair feature can be used to quickly renew IPv4 network connection settings in an attempt to correct common configuration problems.Use the Ping tool to ping your default router by its IPv6 address.To add the IPv6 addresses of additional DNS servers, use the netsh interface ipv6 add dns command.
