Windows vista tip for network troubleshooting
Windows Vista can sometimes cause network adapters to show up as connected to an “Unidentified Network”, sometimes limiting the network to local access only.
There are many reasons that can cause this problem, but some suggested solutions to try are:
• Reset your Router using the web control panel.
• Update your network adapter drivers.
• Temporary disable any Anti-Virus/Firewall package to see if the problem is resolved.
• Try assigning a static IP address to the network card.
• Disable IPv6 on old network cards / routers.
These suggestions may help you narrow down the cause of the “unidentified network” problem.
troubleshooting computer network is among the most important job descriptions of the network administrators, system administrators, network technicians and the IT consultants. A computer network can have different kinds of problems such as it can be infected with virus and spyware, attacked by hackers, accessed by unauthorized users and may face connectivity failure issues due to the faulty network devices or configurations. Following is a list of the basic network troubleshooting commands that are built-in the Windows based operating systems and UNIX etc. The right use of these troubleshooting commands can helps a lot in diagnosing and resolving the issues with your computer network. few more windows vista tips.
Ping is the most important troubleshooting command and it checks the connectivity with the other computers. For example your system’s IP address is 10.10.10.10 and your network servers’ IP address is 10.10.10.1 and you can check the connectivity with the server by using the Ping command in following format.
At DOS prompt type Ping 10.10.10.1 and press enter
If you get the reply from the server then the connectivity is ok and if you get the error message like this “Request time out” this means the there is some problem in the connectivity with the server.
IPconfig is another important command in Windows. It shows the IP address of the computer and also it shows the DNS, DHCP, Gateway addresses of the network and subnet mask.
At DOS prompt type ipconfig and press enter to see the IP address of your computer.
At DOS prompt type inconfig/all and press enter to see the detailed information.
NSLOOKUP is a TCP/IP based command and it checks domain name aliases, DNS records, operating system information by sending query to the Internet Domain Name Servers. You can resolve the errors with the DNS of your network server
Hostname command shows you the computer name.
At DOS prompt type Hostname and press enter
NETSTAT utility shows the protocols statistics and the current established TCP/IP connections in the computer.
NBTSTAT helps to troubleshoot the NETBIOS name resolutions problems.
ARP displays and modifies IP to Physical address translation table that is used by the ARP protocols.
Finger command is used to retrieve the information about a user on a network.
Tracert command is used to determine the path of the remote system. This tool also provides the number of hops and the IP address of each hop. For example if you want to see that how many hops (routers) are involved to reach any URL and what’s the IP address of each hop then use the following command.
At command prompt type tracert http://www.yahoo.com you will see a list of all the hops and their IP addresses.
Traceroute is a very useful network debugging command and it is used in locating the server that is slowing down the transmission on the internet and it also shows the route between the two systems
Route command allows you to make manual entries in the routing table.
Hopefully the above mentioned commands will help you to diagnose the troubleshooting your computer networking problems
