DESCRIPTION

This function enumerates all machines on the current (or specified) domain using Get-DomainComputer, and queries the domain for users of a specified group (default 'Domain Admins') with Get-DomainGroupMember. Then for each server the function enumerates any active user sessions with Get-NetSession/Get-NetLoggedon The found user list is compared against the target list, and any matches are displayed. If -ShowAll is specified, all results are displayed instead of the filtered set. If -Stealth is specified, then likely highly-trafficed servers are enumerated with Get-DomainFileServer/Get-DomainController, and session enumeration is executed only against those servers. 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-DomainUserLocation

Searches for 'Domain Admins' by enumerating every computer in the domain.

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

Find-DomainUserLocation -Stealth -ShowAll

Enumerates likely highly-trafficked servers, performs just session enumeration against each, and outputs all results.

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

Find-DomainUserLocation -UserAdminCount -ComputerOperatingSystem 'Windows 7*' -Domain dev.testlab.local

Enumerates Windows 7 computers in dev.testlab.local and returns user results for privileged users in dev.testlab.local.

-------------------------- EXAMPLE 4 --------------------------

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

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

Searches for domain admin locations in the testlab.local using the specified alternate credentials.
