Very Slow Network

Hello All,

We are experiencing large lag times when browsing shares on machines in our network.  We are running a windows network.  We have about 100 PCs on our network, they are connected in groups of 24 to a switch then those four switches to a main switch.  All machine have a static IP of 192.168.0.___ and a subnet mask of 255.255.255.0

We are finding that browsing the network or access a share on a machine by typing \\machine_name can take a 30 to 50 seconds at times but once you are connected to the machine you are fine.

We are running a 100 network.  

My question is how can we get the network to be more responsive, I have heard that sometimes there can be nic cards that can flood the network, or pc's that broadcast a lot.  What type of software is available to determine where our problems are and give us a suggestion on how to correct it.  Also is there something wrong with the way we have designed our lan?

Thanks in advance.

Mike

It sounds like a DNS or WINS issue.  If it slow only when you are resolving the name then I would focus my efforts there.  If t were broadcast problems, you would see slow traffic constantly.  Try connecting by ip address and see if it speeds up the process.

We are not running DNS or Wins or at least I don't think we are.  How can I troubleshoot to see if it is a DNS or WINS issue?
To check to see if you have an internal DNS...

START | RUN | type CMD click okay | type IPCONFIG /ALL |

Look at the line that says DNS and see if it looks the same as the line that says IP ADRRESS.

the Ip address is that of our ISP it is not the same as the ip address
What kind of network is this?? Do you have a domain? If so why all the shares on differnt Pc's?? Why no a file server? Hmmmm sound like you need to rethink this design as you are forcing 100 machines to broadcast constantly to keep track of each other and resources.

Okay then that kinda rules out a DNS problem...

shinds57 is correct, about using a file server rather then having many shares on many computers...

Also check out which machine is broadcasting the most as in my first post.

Is your network having nt4 server or 98 and less computer?

If not maybe you should try disabling the wins that can make some traffic...

Did you try to scan your network?  I use network monitor from windows 2k server cds...it's not very complicated and can be realy usefull in all situation!

We are running windows 2000 professional.  I only have on cd for Windows 2k is it on that CD?  where is it located?
I dont think that it is on windows 2000 pro....you should check your network with a server....it is on the windows 2000 server disk....go to add/remove prrograms/windows componant and look for management and monitoring tools.  It is network monitor tools
the problem is obviously in the fact that you don't have server on your network, but you can have problems with slow network beacouse you have 5 switches on your network.
