Recently needed to check the uptime of some windows server, mostly to verify that we had rebooted them all.
Quickly found a command line:
There are two options
1 - net statistics server
2 -
SystemInfo |FIND /I "System Up Time"
Be nice to include this in my monitoring program, so it could be quickly queried from a centralized place, or embed this in some windows script that could take a list of them and run it remotely.
Thanks to Rick Mcintosh.
