SysAdmin Sense

Seems the older I get the more I forget. Here's a simple command to find the OS / Service Pack C:\Windows\system32>systeminfo | findstr /B /C:"OS Name" /C:"OS Version" OS Name:                   Microsoftr Windows Serverr 2008 Standard OS Version:                6.0.6002 Service Pack 2 Build 6002

I received the following error message when trying to RDP to a remote server: Remote Desktop cannot verify the identity of the remote computer because there is a time or date difference between your computer and the remote computer.

Found this PowerCLI  code very helpful! Thanks Benj IT Walk Thru: Finding all VMs with thick hard drives : Get-VM | Get-HardDisk | where-object {$_.StorageFormat -eq 'Thick'} | select-object -expandproperty Parent -unique | sort

PowerCLI Notes I was looking to see if a particular server still existed. It had an app licensed by MAC address. This little line of code helped me to find the MAC did not exist. So I built a new VM and gave it this MAC and re installed the app. ~~~~~ Connect-VIServer VSPHERE01 Get-VM | Get-NetworkAdapter | Where {$_.MacAddress -eq “00:50:56:9B:29:1C”} | Format-List
