What is Nslookup.exe?

Nslookup.exe is the Microsoft name server lookup utility. Nslookup is a network utility program used to obtain information about Internet servers. The name nslookup means name server lookup. As its name suggests, the utility finds name server information for domains by the Domain Name System (DNS).It is a command-line program that allows you to lookup name server information, such as what IP address a domain name resolves to or what domain name an IP address resolves to.

Nslookup does not use the operating system's local Domain Name System resolver library to perform its queries, and thus may behave differently to dig (which does). Additionally, vendor-provided versions can confuse matters by using or including output of other sources of name information (such as host files, Network Information Service). Some behaviors of nslookup may be modified by the contents of resolv.conf.

Nslookup operates in interactive or non-interactive mode. When used interactively by invoking it without arguments or when the first argument is - (minus sign) and the second argument is a host name or Internet address of a name server, the user issues parameter configurations or requests when presented with the nslookup prompt (>). When no arguments are given, then the command queries the default server. The - (minus sign) invokes subcommands which are specified on the command line and should precede nslookup commands. In non-interactive mode, i.e. when the first argument is a name or Internet address of the host being searched, parameters and the query are specified as command line arguments in the invocation of the program. The non interactive mode searches the information for a specified host using the default name server.

Nslookup.exe Errors

  1. Nslookup works but nothing else has DNS on standalone Win7 PC.
    Description: Network and sharing center shows both as connected and no internet access. Ipconfig /registerdns brings up the error: Registration of DNS failed: The RPC server is unavailable which seems strange as RPC says its running in services.msc and everything else seems to be OK.

When trying to browse through to a website, it shows the message Waiting for http://xxx.xxx.xxx in the status bar but fails to load the webpage.
  3. Ping (or browser) DNS lookup takes 5-10 seconds yet nslookup results are instant
    Description: Connected to the internet by a USB wifi dongle to broadband router. There are 5-10 second delays before web page loads in browser (chrome and IE). Slight delay, then bang page displays very quicky. Connection monitor indicates 1.6 Mbytes/s, pretty quick for ADSL.
  4. Ping, nslookup for the hostname machine return different results on a multihomed computer
  5. DNS Broke - nslookup Successful But Ping Fails
