Help finding bottleneck

[silvere]

If this is not the right forum please redirect me.

We have recently bought a company and I'm helping them switch over. their network is pretty slow. they are currently using quickbooks with 6-7 people accessing it. roughly 15 computers total. the quickbooks file is around 500mb, I'm not sure if that has something to do with it. People are complaining that quickbooks is slow and I understand that can be an issue with multiple users. but they are also have spreadsheets drag and freeze up.

anyways, we are switching to microsoft navision and going live on the 1st. I've also noticed a slow down on navision which we connect remotely to. so, it's not on the same server as quickbooks.

any suggestions?

What other apps / services are running.

Start looking at performance logs, create some monitors on pagefile useage, memory use etc get a bench mark and see what is running high.

Also what sort of network are you running 10/100/1000?

I was wrong I'm on a 2003 server here. I checked the logs as suggested and sure enough when they run a report the disk usage and processor spike. other random moments they all jump up pretty high, but I don't think anyone is accessing it at that moment.

But....I don't think that's my major problem right now. I think my problem is more the network speed because as of the 1st we will only be using that server as a file server. everyone will be connecting back to the main office with navision. that's what I'm mainly worried about running slow. we are on a 10/100. do I need to switch to a gigabit?

when you say "everyone will be connecting back to the main office"

Do you mean its slow for them in the remote office to access your servers in the main site?

Ifso the the internet connect could be to blame.

Also if you look at the processes what are causing the spikes in mem and cpu usage?
