Static Route??

For sake of confusion i will try and explain this the best i can. Lets just say i have a Cisco 4500 router. Now E0 is the outside world, E1 is my internal network, now what i want to do is add an OWA server on E3. I have it hooked up now but no connectivity, what kind of cable should it be crossover right?? And do i need to add a static route so i can access it internally and externally?

Your ISP needs to know about that IP subnet. If you're NATing then add a static NAT entry to your NAT config. If you're not, then you ought to be using an IP address they already know you have anyway.

Then if they are running DNS for you, you need to give them the external hostname you want and the IP address.

Yes, you need a crossover cable. If everything that needs to access it uses the 4500 for their default gateway (regardless of interface) then you won't need a static route. If things connected to other routers need to talk to it, then whatever you are doing so they can talk to your current stuff on the 4500, do the same for this new subnet.

shouldnt i make the default route on the OWA server the IP of the interface its connected to, because right now i cant ping the router from it and vice versa, but i do show up, up.

Yes, you do need to do that. But they should be able to ping each other regardless if their subnet masks match, as they would be on the same subnet and just ARP for each other. Something else is going on otherwise.

Make sure that speed and duplex configuration match, etc. Depending on the 4500 card you may need to set the physical interface (MII vs 4RJ-45).
Check the ARP tables on both devices (sho ip arp on the router). Do they have correct MAC addresses for each other?
