Obtain the domain name on a workstation or server

A:

Sorry just noticed the windows tag, see list of network functions

all is well, except that all the network API are based on the fact that you configured a domain on the computer. what if you didn't? how can I get the domain the computer is connected currently?

Sorry don't do much windows sysadmin stuff, that's why I posted the link to the entire list of functions rather than pick one.

Are you after the DNS domain configured via DHCP?

gwell 2009-10-21 20:40:28

I think so. I mean, think about it this way. you have a brand new computer that you just connected to the network. You received your IP and you can connect to the internet but you are NOT formally part of the domain. You will not find the "somedomain.com" anywhere on the usual places (registry or otherwise).

wonderer 2009-10-21 20:57:07

So, the domain does not appear in HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters ? You might try DhcpRequestParams().

gwell 2009-10-21 21:12:04

thanks, but how is that different from the other APIs? can you give me a sample snippet that can provide the DNS name?
