Option Explicit
Dim objWMIService, objComputer, colComputer, strComputer

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _

& strComputer & "\root\cimv2")
Set colComputer = objWMIService.ExecQuery _
("Select * from Win32_ComputerSystem")

For Each objComputer in colComputer
Wscript.Echo objComputer.UserName & " is logged on"
Next

' End of Sample Script. Who is logged on?

1. we have to use NTLM for authentication in our environment which can be done by executing 'cscript adsutil.vbs set w3svc/1/root/NTAuthenticationProviders "NTLM"
2. modify RSWebApplication.config and comment out the line

network performance issue

we had a significant network performance slowdown back to 1 week ago which initially we thought was caused by server performance.
After tuning up a few servers, the situation seems to be improved but the system response is still notably slow.
Eventually we got to look at the firewall (Cisco ASA which replaced the pix firewall a week ago, the CRC error seems to be introduced at that time).
I did a ping from the Cisco ASA firewall and observed packet loss, the network guy later discovered CRC errors using show interface command (I did same thing but didn't notice the CRC error!) which apparantly is the root caused of the problem.
I have to admit though, by looking at the server side of things, we did discover a few performance bottleneck and improved the application performance. I guess this can also be noticed when the netowrk is back to normal.

Good lesson.
