New Server not seeing AD Server

I have abrand new AD server with DNS running etc. I am
able to ping my other system which I am building as an
exchange server, but the exchange server is not able to
ping AD. Is there rights for the new server that need to
be assigned in AD, becuase I have the two connected by a
switch, and it is funny how AD can see everything, but my
other server can not ping AD.

One-way ping only

If you can ping other computers and other computers can't ping your
computer, this is often caused by an improperly configured firewall
on you computer. For example, ICF should not be enabled on LAN NIC.
