Windows: Backup with diskshadow.exe

Hello,

Windows Server 2008 and alter version are shipped with a tool called diskshadow. This program can be used to create snapshots of disks and expose them as Folder or as DriveLetter means files are in a consistent state and you can save openfiles.

Some examples. Starting diskshadow. It accept a  parameter /l  for a logfile. And a Parameter /s for a (diskshadow) script file to execute. diskshadow has the same “look and feel” like diskpart 🙂  and start with a prompt:

Windows: Cannot bring up Cluster Networkname Resources

Hi,

a customer has, accidentally, deleted multiple Active Directory Computer objects which correspond to Network Name Resources of a Windows Cluster 🙁 .

The cluster network name itself was also affected and no backup of the AD Database to restore the objects was available.

All solutions that I’ve found to get the cluster working again are based on the restore of the AD objects.

But there is also another way respective hack 🙂 . This works for me on a Windows 2008 R2 Cluster.
Typical error are:

  • Event ID 1207 is logged to the Eventlog: “Unable to get Computer Object using GUID” “There is no such object on the server.”
  • Or in the C:\Windows\Cluster\Reports\cluster.log file (exported with cluster.exe log g)
    Network Name <Clustername>: Unable to Logon. winError 1326

Windows: Determine uptime from command line

Hi,

unlike Linux, Windows has no builtin uptime command to see when the operating system starts.

But nevertheless it’s possible. Use the systeminfo command.


c:\> systeminfo | findstr /i time
System Boot Time:          05.06.2014, 21:05:06
Time Zone:                 (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna

Note: If you have installed a language different then english replace time as filter which applies to your language.
