Over 200 fixes – from PowerShell 2.0

Network Locations using PowerShell

So you can’t manage your network locations from PowerShell by default.  Here is a great dll you can add to expose network locations.
Download and extract the dll into your scripts directory from http://archive.msdn.microsoft.com/NLM  Look in \NLMCSharp.zip\NLMCSharp\obj\Debug


Add-Type –Path .\Interop.NETWORKLIST.dll
$nlm = new-object NETWORKLIST.NetworkListManagerClass
$nlm.GetNetworks("NLM_ENUM_NETWORK_ALL") | select @{n="Name";e={$_.GetName()}},@{n="Category";e={$_.GetCategory()}},IsConnected,IsConnectedToInternet

Replacement Commands

Netdom http://blogs.technet.com/b/heyscriptingguy/archive/2012/02/29/use-powershell-to-replace-netdom-commands-to-join-the-domain.aspx

UPDATE - PowerShell 3.0 now includes a last switch for get-content
get-content <file> -last 5
To watch a log file ...
get-content <file> -wait
but not exactly the same functionality. So a better way is to get the command from Microsoft.

Tail is included in the 2003 Resource Kit and works well in Server 2008 environment.
