Hi, I'm kinda new to linux. I have a Compaq Proliant 1850r which I have just installed Core 2 on. Everything is up and working great except one thing:

When I am phiscly connected and logged into my server (meaning i have my keyboard mouse and monitor plugged into it) everything works great. Apache is up and running, I can ping all other devices on my network, SSH daemon is running, Samba is going, I can see all the windows machines. BUT when I go back to my Windows box I can't ping my server, SSH into it, or access the website through the local IP or the public IP, keeps telling me that the connection was refused. I have the firewall disabled but my server won't accept ANY incomming requests...

Any help at all would be awesome. Thanks in advance.

Just to check, try
iptables -L
on the box. Also, try ssh-ing into the box from the box itself and see what happens.
Try via specifying the ip address and also try via the DNS name.

if it is denying ssh try typing

# allow SSH on all interfaces , eth0 eth1 etc
iptables -A INPUT -p tcp --dport 22 -m --state NEW -j ACCEPT
