DESCRIPTION

This function enumerates all machines on the current (or specified) domain using Get-DomainComputer, and enumerates the available shares for each machine with Get-NetShare. It will then use Find-InterestingFile on each readhable share, searching for files marching specific criteria. If -Credential is passed, then Invoke-UserImpersonation is used to impersonate the specified user before enumeration, reverting after with Invoke-RevertToSelf.

EXAMPLES

-------------------------- EXAMPLE 1 --------------------------

Find-InterestingDomainShareFile

Finds 'interesting' files on the current domain.

-------------------------- EXAMPLE 2 --------------------------

Find-InterestingDomainShareFile -ComputerName @('windows1.testlab.local','windows2.testlab.local')

Finds 'interesting' files on readable shares on the specified systems.

-------------------------- EXAMPLE 3 --------------------------

$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force

$Cred = New-Object System.Management.Automation.PSCredential('DEV\dfm.a', $SecPassword) Find-DomainShare -Domain testlab.local -Credential $Cred

Searches interesting files in the testlab.local domain using the specified alternate credentials.
