HI, I have installed Windows server 2008 and server 2003 on 2 computers connected through a router to connect Internet. I can ping 2008 from 2003 but cant ping 2008 to 2003. i have configured static IP addresses on both servers. I also have disabled windows firewall on 2008 still cant ping. Earlier i installed server 2003 on both computers and were connected with same router and the connectivity was fine. They were able to ping but since i have upgraded it to server 2008 it has stopped. Please help me Thanks in advance raul
