Uptime of system on network

[Brian Henry]

does anyone know of an easy way to say how long has a specific system been
up and running? I just need to get back the uptime of the servers on our
network for a report, they are all in a Active Directory domain... needs to
be in C# or VB.NET preferably. thanks!

Brian,

You could just have a service running on the server which will take note
when it starts. Then, to get the uptime, you can call to the service, and
take the difference between the current time and the time that the system
went up.

You could use remoting to access this information as well.

Hope this helps.

You might check the System EventLog for the youngest event like #6009 (forr
boot up). This can be done with a pure .net solution.

Another possibility is Environment.TickCount. This returns the Number of
milliseconds since the last system bootup. When the System runs for more
than 24.9 Days (or 49.7 days, when you are pInvoking GetTickCount), the tick
count will wrap around, though.

You could use System.Management classes to query the servers WMI class
"Win32_Operatingsystem" "Lastboottime" property.
