Describe the bug

When executing the powerview share_finder module, no results are returned unless the ComputerName parameter is populated. When I import the powerview.ps1 script and attempt to run the Find-DomainShare function manually, I get the following error:

Get-DomainSearcher : A parameter cannot be found that matches parameter name 'Properties'.
At C:\powerview.ps1:6323 char:44
+         $CompSearcher = Get-DomainSearcher @SearcherArguments
+                                                                               ~~~~~~~~~~~~~~~~
    + CategoryInfo                   : InvalidArgument: (:) [Get-DomainSearcher], ParameterBindingException
    + FullyQualifiedErrorId      : NamedParameterNotFound,Get-DomainSearcher

[Find-DomainShare] No hosts found to enumerate
At C:\powerview.ps1:18928 char:13
+         throw '[Find-DomainShare] No hosts found to enumerate'
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo              : OpeartionStopped: ([Find-DomainSha...nd to enumerate:String) [], RuntimeException
    + FullyQualifiedErrorId : [Find-DomainShare] No hosts found to enumerate

My PowerShell-fu is nonexistent but looking at the powerview.ps1 code, the one thing that jumped out at me in the Get-DomainComputer function was that there are a couple of extra brackets on line 6259 where the $Properties param is defined:

        [ValidateNotNullOrEmpty()]
        [String[]]
        $Properties,

I see that Find-DomainShare calls Get-DomainComputer, which calls Get-DomainSearcher so it makes sense that Get-DomainSearcher is failing due to a missing required parameter when it is getting called from Get-DomainComputer. So it would seem that any module that relies on this Get-DomainComputer function is going to fail.

To Reproduce

Steps to reproduce the behavior:
Execute the powerview share_finder module without any parameters.

Expected behavior

The module is supposed to find all computers in the current domain and use them as targets for discovering shares.
