Just a thought

I’ve working with WMI a lot recently and frequently seen things like this

Get-WmiObject -Class Win32_OperatingSystem -ComputerName dc02

Get-WmiObject -Class Win32_ComputerSystem -ComputerName dc02

Get-WmiObject -Class Win32_LogicalDisk -ComputerName dc02

Each of these has to create a connection


$sb = {
Get-WmiObject -Class Win32_OperatingSystem
Get-WmiObject -Class Win32_ComputerSystem
Get-WmiObject -Class Win32_LogicalDisk

Invoke-Command -ScriptBlock $sb -ComputerName dc02

more efficient

In some cases yes depending on what you want to do with the information. Especially if need to filter data

Good method. But it requires WS-Management service running on the destination. On older servers it might be an issue.

Yes it does but it can be installed on Windows 2003 and above.

Windows 2000 isn't really an issue - its a year out of support and should be on the way out of the organisation if it hasn't gone already.

OT: for Windows 2000 boxes: it was easy to get rid of them when they were on the physical boxes - scheduled hw refresh would take care of it. But now after p2v'ed them, nobody bothers to touch them - the "if it ain't broken, don't fix it" mantality :(

Agreed - I know of people still finishing off NT4 removal - but they do leave a security hole and have to go eventually
