I have a strange situation here. A new client has asked me to help seperate there networs for them but at the same time allow for sharing of a few resources. (Printers, drives, ect.) To start the network is setup as follows. Have a T1 coming in to a 4 port swtich. From there there is a 2 cables, one to router1 and another cable to router2. From router 1 we have a cable to DC1 running 2003 server. And another cable to 2 24 port switch. On router2, there is only a cable going to another dc2 for a totally seperate domain. No switch there at all. Now everyone in the building is connected to the switchs and set on router1 for internet and network shareing ect. Their previous IT dept told them it was impossible to have two networks working together at the same time. So instead of setting up dc2 for sharing of drives they put share point on dc2, and set everyone up to go out throught the internet and then back in to hit the sharepoint. My job is to seperate the two networks but still be able to have a little sharing between the two. My idea was to plug router1 into 24 port switch1 and router2 into 24 port switch2. But then how would I solve the problem of setting up sharing between the two?
