I'm querying the CIM provider on a specific host and and getting "The SSL certificate is expired" ona particular host. The exception message powershell brings back is "Exception Message: Cannot bind argument to parameter 'CimSession' because it is null." The self-signed cert on the vmhost 5.0 host expires in 2026. What other certificate could be returning this error? I'm curious because I run this against other hosts built around the same time. The hosts are on the same network and in the same cluster. I tried recycling the CIM_server process, same error. I'm running on a windows 2012 R2 server with powershell 4. Any ideas, I'd be curious.
here is the script. I'm using
param
(
$ServerListFile=$(throw "Please specify file containing servers"),
$Output="MemoryStatsforHost",
$OutputErrors="MemoryStatsforHostErrors"
)
Import-module CimCmdlets
function Log([string]$path, [string]$value)

Add-Content -Path "$($Path)$($LogDate).txt" -Value $value
}

$serverlist=get-content -path $ServerListFile
$StartDate = Get-Date
$LogDate = "$($StartDate.Month)-$($StartDate.Day)-$($StartDate.Year)-$($StartDate.Hour)-$($StartDate.Minute)-$($vCenterServer)"
Write-Host "Gathering VMHost objects"
Log -Path $Output -Value "Starting process as $($Cred.Username) at $($StartDate)"
Log -Path $Output -Value "Server,Caption,MaxMemorySpeed,CapacityGB"
foreach($server in $serverlist)
{
