Wrote a small script to write to my System Event Log and restart my servers

```auto
$Server = hostname
New-Eventlog -logname System -source "System Restart"
Write-EventLog -Logname System -source " System Restart" -EntryType Information -EventId 99 -Message "System Restart for Security updates."

```

Write-EventLog : The source name " System Restart" does not exist on computer “localhost”.  
At line:1 char:1

- Write-EventLog -Logname System -source " System Restart" -EntryType I …
- 

```auto

```

- CategoryInfo : InvalidOperation: (🙂 [Write-EventLog], InvalidOperationException
- FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteEventLogCommand

I ran this command

[system.diagnostics.eventlog]::SourceExists(“System Restart”)  
True

&nbsp;

&nbsp;

Any Ideas?

&nbsp;

Thank you

Tom

Hi Tom,

I saw a couple of errors, after fixing I tested and it worked.  
1st. The codes as posted used smart quotes (as in MS-Word quotes). Change them to straight double-quotes or single-quote.  
2nd. You have a leading space " System Restart" in the Write-EventLog

`$Server = hostname
New-Eventlog -logname System -source “System Restart”
Write-EventLog -Logname System -source “System Restart” -EntryType Information -EventId 99 -Message “System Restart for Security updates.”`

Hi GNART

OMG a little space in the wrong place.

Thanks for the quick response.
