## SYNTAX

```
Test-AdminAccess [[-ComputerName] <String[]>] [-Credential <PSCredential>]
```

## DESCRIPTION
This function will use the OpenSCManagerW Win32API call to establish
a handle to the remote host.
If this succeeds, the current user context
has local administrator acess to the target.

## EXAMPLES

### -------------------------- EXAMPLE 1 --------------------------
```
Test-AdminAccess -ComputerName sqlserver
```

Returns results indicating whether the current user has admin access to the 'sqlserver' host.

### -------------------------- EXAMPLE 2 --------------------------
```
Get-DomainComputer | Test-AdminAccess
```

Returns what machines in the domain the current user has access to.

### -------------------------- EXAMPLE 3 --------------------------
```
$SecPassword = ConvertTo-SecureString 'Password123!' -AsPlainText -Force
```

$Cred = New-Object System.Management.Automation.PSCredential('TESTLAB\dfm.a', $SecPassword)
Test-AdminAccess -ComputerName sqlserver -Credential $Cred
