    .EXAMPLE
        Invoke-FileServiceIntegrityCheck -SearchPath \\server1\share -FileCount 25 -ComputerName server2 -ServiceName intergrator -SendReportTo bob@example.com -EmailDomain example.com -Mailserver mail.example.com -Credential (Get-Credential)

        Checks the folder \\server1\share to see if there is 25 or more files. If it does, it will restart the service named intergrator on server 2.

Dear Watcher,<br>
<br>
During my last check there were <b>$($Files.Count)</b> files inside <i>$SearchPath</i>. The Integrator was stopped on <b>$($StopTime.tostring())</b> and started on <b>$($StartTime.tostring())</b>. There are now <b>$($files2.count)</b> in <i>$SearchPath</i>. Please investigate on why the $ServiceName failed on $ComputerName.<br>
<br>
<br>
Thank you,<br>
<i>$ServiceName WatchEye</i><br>
