## DESCRIPTION
Enumerates all domain controllers from the specified -Domain
(default of the local domain) using Get-DomainController, enumerates
the logon events for each using Get-DomainUserEvent, and filters
the results based on the targeting criteria.

## EXAMPLES

### -------------------------- EXAMPLE 1 --------------------------
```
Find-DomainUserEvent
```

Search for any user events matching domain admins on every DC in the current domain.

### -------------------------- EXAMPLE 2 --------------------------
```
$cred = Get-Credential dev\administrator
```

Find-DomainUserEvent -ComputerName 'secondary.dev.testlab.local' -UserIdentity 'john'

Search for any user events matching the user 'john' on the 'secondary.dev.testlab.local'
domain controller using the alternate credential

### -------------------------- EXAMPLE 3 --------------------------
```
'primary.testlab.local | Find-DomainUserEvent -Filter @{'IpAddress'='192.168.52.200|192.168.52.201'}
```

Find user events on the primary.testlab.local system where the event matches
the IPAddress '192.168.52.200' or '192.168.52.201'.

### -------------------------- EXAMPLE 4 --------------------------
```
$cred = Get-Credential testlab\administrator
```

Find-DomainUserEvent -Delay 1 -Filter @{'LogonGuid'='b8458aa9-b36e-eaa1-96e0-4551000fdb19'; 'TargetLogonId' = '10238128'; 'op'='&'}

Find user events mathing the specified GUID AND the specified TargetLogonId, searching
through every domain controller in the current domain, enumerating each DC in serial
instead of in a threaded manner, using the alternate credential.
