collecting a count of errorlogs using posh

Hi, I am running a script to collect a count of all errors in the current error log using smo, as below:$sqlServer = new-object ("Microsoft.SqlServer.Management.Smo.Server") "MYSERVER"$logs = $sqlServer.ReadErrorLog() | where {($_.Text -like "Error*" -or $_.Text -like "*Fail*") -and ($_.Text -notlike "*Found 0 Errors*")};$count = $logs.Count$countand then dumping this into a monitor database.This works fine for most servers, but I have a 2005 cluster that for some reason won't return the count. If I just read the error log into console that works fine, but the .Count method disappears completely from the object. It is like, for this server, the object returned from $sqlServer.ReadErrorLog() is different to the rest of the servers.Any ideas?Thanks for reading.
