Tracer cannot be disabled - powershell error

Hi,

I have this CRM 2011 rollup 6 that has no documentation on how tracer was enabled and so far I tried the registry and dignose tool without success

powershell is throwing this error

PS C:\Users\svc_crminstall> $setting = Get-CrmSetting TraceSettings
Get-CrmSetting : The remote server returned an error: (404) Not Found.
At line:1 char:26
+ $setting = Get-CrmSetting <<<<  TraceSettings
    + CategoryInfo          : NotSpecified: (:) [Get-CrmSetting], WebException
    + FullyQualifiedErrorId : System.Net.WebException,Microsoft.Crm.PowerShell.GetCrmSettingCmdlet

any suggestions
