The person who set up are network, did one of the worst jobs i have ever seen. Nothing is in order, there are wires all over the place, and the configuration is odd. We have 3 T-1's coming in, two are for the phones and one for the internet. The phones are totally independent from the computers and they are fine. The other T-1 comes into a Cisco 1721 router and then out to a linksys EF3124 24 port switch. From there, there is one more 24 port switch, and a wireless router. The server is plugged into a port on the back of the wireless router (WRT54GS). When i took the server off the wireless router and plugged it into the switch, none of the computers on the network could find it. I am new to networking and my boss couldn't figure it out either, so any ideas on what is causing this would be appreciated. Thank you.
