How to find netbios name from ip address

At its simplest, the IPConfig command will display basic IP address configuration information for the device. Simply type IPConfig at the Windows command prompt, and you will be presented with the IP address, subnet mask, and default gateway that the device is currently using. Doing so causes Windows to display IP address configuration that is much more verbose.

This is also the command that you will have to use if you want to see which DNS server the Windows device is configured to use. From there, you can type host names in an effort to see if the DNS server is able to resolve the specified host name.

IP networks use routing tables to direct packets from one subnet to another. To do so, simply type Route Print.

The cool thing about the Route command is that it not only shows you the routing table, it lets you make changes. Commands such as Route Add, Route Delete, and Route Change allow you to make routing table modifications on an as needed basis. The changes that you make can be persistent or nonpersistent, depending on whether you use the -P switch. Earlier, I talked about the Ping utility and the Tracert utility, and the similarities between them.

As you might have guessed, the PathPing tool is a utility that combines the best aspects of Tracert and Ping. Entering the PathPing command followed by a host name initiates what looks like a somewhat standard Tracert process. Once this process completes however, the tool takes seconds five minutes to gather statistics, and then reports latency and packet loss statistics that are more detailed than those provided by Ping or Tracert. Perhaps the most useful of the network utilities that are built into Windows is NetDiag.

The NetDiag command is designed to run a battery of tests on the computer in order to help the technician figure out why the computer is experiencing networking problems. Entering the NetDiag command by itself will cause all of the available tests to be run. In some cases, NetDiag can not only identify problems, but can also fix those problems. The Windows operating system is jam packed with command line utilities. Many of these utilities are left over from operating systems that were introduced decades ago.

Even so, the utilities that I have discussed in this article are every bit as useful today as they were when they were first introduced. Brien Posey is a freelance technology author and speaker with over two decades of IT experience. Prior to going freelance, Brien was a CIO for a national chain of hospitals and healthcare facilities.

In addition, Brien has worked as a network administrator for some of the largest insurance companies in America. NetDiag hasn't been included with Windows since XP. The goal of what is now called Intrusion Detection Systems IDS was to detect a malicious attacker before an anti-virus, Trojan horse, or worm was used to strike. If the attacker was able to strike the network, security professionals would dissect the code. Once the code was dissected, a response or "fix" was applied to the infected machine s.

It only gives you a small glimpse into what can be happening. The real work horse of the Netstat commands is netstat -bao. It tells you all your connections and the Port and Program that they belong to. Netstat has lots of great options. Is there any software free that would give those details.

What's a Windows equivalent to "smbutil statshares -a" that can tell me how my Windows client is connecting to the Windows server? Finally, explanations can't decide between advanced and beginner-level. You need to flesh out each on simpler terms if they're to be understood.

Admins who can understand things like these don't need to even read the article:. Maybe you can help me, Brian. I'm looking for a utility that I can setup in a TASk to check what IP my ISP has assigned my connection and email that info to a friend sho remotes in to diagnose and do maintenance on my system. Since most ISP assign dynamic IP's, without know what it is currently they can't remote in via RealVNC or other remote access programs without my being present to supply the correct address to us to connect.

Is there anything available or controllable klede to achieve this? We both use Outlook, so the msg generated with my currently assigned IP would need to be send as a mgs and it needs to be able to be setup as a TASK so it's kept current. Pre, NoIP does that for free. You just need to register and check-in once a month to renew the connection.

Set up a static IP through your router web interface page. Though you can set up a static IP for a device and then manually config that device with the static IP. It sounds like a lot, but you can do it with ease with a youtube video tutorial. Basically run ipconfig and take a picture of that info and then reassign that info when you set up a static non changing IP address.

Is this normal? I'd say this is probably a lot more common than people realize. So if a laptop has both Ethernet and wifi, you turn it on and the Ethernet connects first, then the wifi, the wifi gets the DNS, but the Ethernet responds faster so it gets the NetBios. I would say that would be somewhere between unusual to abnormal. You could have a machine with multiple IP addresses, which would be unusual.

If you are getting this with result when the server in question has only 1 IP address, it is abnormal.

Is there somewhere specifically that this would be configured, as to my knowledge it should not be set up like this. Can you post an example of what you are pinging as far as the netbios and fqdn name goes? See if get back different answers.

    Assuming Windows machine here Two things to note Second thing is nslookup uses whatever your primary DNS server is. The results nslookup return are the results from your primary DNS server, i. This may or may not be the same results you get from ping because of the aforementioned name resolution order. Assuming you don't have host files set for sanity sake. Unless you have search domain suffixes configured, your DNS query will fail also, which leaves fall back to NETBIOS for the resolution, which it relies upon responses from other Windows machines for, and they may or may not be correct.

    The reasons for the difference can't really be pinpointed with the given information, but a machine with multiple IP addresses as mentioned is the most likely reason. One possible cause of multiple IPs is a laptop with both ethernet and wifi active at once, which can cause confusion and errors. Often there's a bios setting you can enable that will automatically disable wifi whenever ethernet is detected.

    Check your DNS details. There should be some old entries present who pointed to some other ip. After lmhosts, look at hosts file. Native IP functions like ping will look at hosts, but never lmhosts.
