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.

(see image below) Turned out the server had lost it's connection in the domain. Dropping and re-adding to the domain fixed the issue.

Posted on February 29, 2012 by Daniel Are you using remote desktop against a Windows 7 machine and gets randomly disconnected? Many organizations are enabling Remote Desktop through Group Policy. There is a little problem with this approach. Normally, Remote Desktop is turned off by default, you can see the default setting in this registry key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server] “fDenyTSConnections”=dword:00000001 When you enable the Group Policy Computer Configuration > Policies > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections > Allow users to connect remotely using Terminal Services, it will create the registry key fDenyTSConnections under [HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Terminal Services] But everytime your computer does a gpupdate...

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

Some day I'll understand. VMware Update Manger - Why does it take so long to scan a brand new host? JAVA - Why does it peg the processor with only one JAVA app running? Windows download - Why does the time jump from 10 minutes to 4 hours then back to 30 minutes?
