If you need to know the total uptime on a server, you have a few options. One way is to enter the following command at the command prompt:
C:\> net statistics server | more
Statistics Since... will appear at the top of the screen, which will display the time since the Server service started. Keep in mind that if someone has issued the Net Stop and Net Start commands, the displayed uptime will be incorrect.
Windows NT's Performance Monitor is also an option, which you can access by going to Start | Programs | Administrative Tools | Performance Monitor. One of the Performance Monitor counters for the System object is System Uptime.
In addition, the Server Information command-line utility (Srvinfo.exe), included in the Windows NT Resource Kit, also displays total uptime, which you'll find in the last line of output.
However, the Server Information tool also provides a lot more additional information. Its output also lists details about the server, including the version, service packs, hot fixes, services, installed hardware, and more.
When you run the Server Information tool, the output will look something like this:
Server Name: NTSERVER
NT Type: WinNT Server
Version: 4.0, Build = 1381, CSD = Service Pack 4, RC 1.99
IP Address: 188.8.131.52
CPU: x86 Family 6 Model 3 Stepping 3
Drive: [FileSys] [Size] [Free]
System Up Time: 124 Hr 18 Min 5 Sec
You can also use switches with the command to return less or more information.
