Tool to monitor slow network connections?

Hello Experts,

I have a problem that I want to troubleshoot and I'm not sure how.
We have some random slowness in our network that is effecting logons of our students.
I do not have access to our switches, firewalls, or any of that information.  

I have already confirmed on my end that all domain controllers are functioning properly, I have removed almost all of the group policies applying, the same configuration has been duplicated in other labs, yet, we still have some slowness at weird times.  I've seen it myself while on one of the lab workstations.  Everything just hung and then all the sudden it unfroze and all was well.  I couldn't connect to anything while it was going on.

I have network monitor but have yet to figure out how to connect it to a remote system.  Is there any tool that is free that you could recommend to troubleshoot this?  I can ping the systems when this is going on, but a lot of the windows services that are hanging are not using ping.... I don't think?

Any help is appreciated.

Thank you,

Karen

Ruling out bandwidth issues would be a priority. You'll need access to your switches for that, also look at the servers being accessed. What is their cpu, ram and network activity like? Also check disk read and write queues on the servers.

You can also use wire shark on a PC to capture network traffic during problem times and see what can be seen at a packet level.

I do not have access to the switches :(.  The servers all check out fine.  I checked them previously and made adjustments accordingly.  

Can I use wire shark to monitor remote systems?

Have you checked the server disk io queues like I said?

No, wire shark runs and listens on the local PC. You could start it running then switch user to capture their traffic.

Thank you.  I do not have access to the switches and am assured they are working ok.  You all confirmed what I thought I would need access to this.

There really is no solution for this, it's too vague of a issue to determine at this time.
