   You can also do this with the get-dns cmdlet that is included in NetCmdlets.

   NetCmdlets has a free hobbyist license listed on its sales page too.

   @seaJhawk You’re welcome

   @Lance Robinson Yeah, “hobbyist” licenses remind me a bit of the whole “first hit’s free” marketing plan ... but I didn’t even think theirs might support looking up different types at once, good job.

   I should check theirs out to see how they format their output. This class from CodePlex is dying for a decent ps1xml format file with some scripting to unwrap things.

   I’m having some issues on PS1 with the install. After running the install script I don’t see any new snapins or the get-dns cmdlet.

   I’ve pasted the results of the install here and the contents of the _installed.InstallLog file follows.

   Ok, the install.ps1 script just registers the snapin (although it should have made a copy named “PoshNet_installed.dll” not just “_installed.dll”, so that’s weird).

   Basically, it just runs InstallUtil.exe and it’s really for my purposes in development, because it copies the dll before registering it, so I can recompile even if the dll is loaded in a host.

   Assuming the install worked correctly, neither of the commands you ran is the right one to find it. You need to check for registered snapins, because the Install.ps1 script doesn’t Add-PSSnapin unless you pass it the -Add parameter.

   The full process is like this, and if you’re on Vista, you have to run install.ps1 in an elevated console. I’ve added this to the main post, but basically, you need to do something like this:

   Extract-Archive PoshNet.zip      # Unzip the archive somewhere...
   .\Install.ps1 PoshNet.dll        # Run InstallUtil on the assembly
   Get-PsSnapin -registered PoshNet # Verify that PoshNet is installed
   Add-PsSnapin PoshNet             # Load it. (Add this to your profile?)
   Get-Command -PsSnapin PoshNet    # Verify that it is loaded...

   That worked great!

   And amazingly, you managed to do something that the big boys (err… other big boys) can’t seem to do – you provided one snapin that works in both 32-bit and 64-bit PowerShell. I’m not sure if you intended to do that or not, but explaining it would sure make a great blog post because there are a lot of folks out there who need some help.

   You Rock!

   Hm? Was I not supposed to be able to do that?

   Well, I’m honestly not sure what I did differently than anyone else. It’s a pretty straight-forward 32bit assembly project, with my cut-and paste version of a PSSnapin module. Anyone who wants to, is, of course, free to work from my GPL project template
