Slow network - Network utilization question

Posted on 2011-04-20

I have a client who's been having lots of network issues.  Is there a way for me to check the utilzation w/o having to own a CCNP?  I check the NIC performance reviews on the servers and they are always under <25% but half of the users complain that they 'network' is slow when accessing their DB server and file server (2 different servers).  If I remote desktop or VNC into the servers, it 'feels' fine - I don't notice any lag.  If I log into a workstation or two - I sometimes notice some cursor lag but figured it was due to their wallpaper coming across.

No streaming radio.

I just want to see if there's a way for me to tell how much of their 1GB switch is being used (non managed) and if there's a way for me to see if one workstation is saturating the nertwork somehow.

    What brand/model switch?

    Accepted Solution

    I used LAN Speed test and picked a workstation and ran it to all 3 servers at various times.  One of the servers NIC was actually taking down the whole network (it had VERY slow speeds).  We decomishioned it last week and the network performance improved.
