Hello, this is my first time actually posting on this site, I am a student for Network Administration and I was recommended to come here from a few people.

The office network I'm on has around 25 workstations connected to a server, we have an Excel file that's used frequently and is 200MB. When people view it, the network starts slowing down, this may be a coincidence though I'm not sure if it is the problem or not. This network has a lot of issues that occurred before I came here and I'm trying to help them reassemble it.

The network itself is generally slow, which is why I'm not sure if it is the file itself. Your help is appreciated, thank you.

P.S.

I'll probably be having more network related issues in the future.

if it were me i would start by looking at the switches configs (since these are managed switches) and see how they are currently setup......the previous admin could have setup vlans, QOS, etc. that you will want to know about.....once i found out what the switches are setup to do i would probably setup a packet sniffer to see what traffic is on the network....this could help identify where you might be having issues......

also....hopefully all pc's are running at 100 meg and not 10......i have been through a similar situation and found that each pc was only running at 10 mg and half duplex.....i found multiple 10 mg hubs.....i felt like i had gone back in time.....hope this helps
