## SYNTAX
```
Find-DomainShare [[-ComputerName] <String[]>] [-ComputerDomain <String>] [-ComputerLDAPFilter <String>]
[-ComputerSearchBase <String>] [-ComputerOperatingSystem <String>] [-ComputerServicePack <String>]
[-ComputerSiteName <String>] [-CheckShareAccess] [-Server <String>] [-SearchScope <String>]
[-ResultPageSize <Int32>] [-ServerTimeLimit <Int32>] [-Tombstone] [-Credential <PSCredential>]
[-Delay <Int32>] [-Jitter <Double>] [-Threads <Int32>]
```
## 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.
If -CheckShareAccess is passed, then
\[IO.Directory\]::GetFiles() is used to check if the current user has read
access to the given share.
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-DomainShare
```
Find all domain shares in the current domain.
### -------------------------- EXAMPLE 2 --------------------------
```
Find-DomainShare -CheckShareAccess
```
Find all domain shares in the current domain that the current user has
read access to.
### -------------------------- EXAMPLE 3 --------------------------
```
$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
```
$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
Find-DomainShare -Domain testlab.local -Credential $Cred
Searches for domain shares in the testlab.local domain using the specified alternate credentials.
