Divine,
1-Router is doing the DHCP so there is no need to have static IP in either computer.

2- don't mess around with DNS and ICS, DNS is provided by your ISP and ICS is done through you Router.

3-Set you IP in both machine to dynamic and then try to ping your router (Gateway) and the server.

Q; is your computer and server both connected to the LAN ports of the router ? can you make sure that you did not connect either the server or the client system to the DMZ port (if you have one ).

4- check out the port setting / policy in your router to make sure you did not block any thing to either systems.

Let us know how that goes.

t304pk,
ISA server is security gateway of any network and trust me if you don't have the authority to log into the system setting then there is no way to get around the security policy, ISA server is VERY efficient in port blocking so don't even think about it.

Cheers
