networks

Hi guys.
My server running 2003 r2 gave me a snap-in error message when trying to open the DHCP consol. I went on to give clients static ip while trying to fix the dhcp issue. but now some of the clients can ping each other some can’t. when the other ping each other, they cannot share network resources. it give error” network path not found” could be caused by the DHCP issue???
plis help guys
thanks in advance
