Can't connect in any way to an internal domain XP SP-2 workstation outbound works fine

I have a problem with a client on a W2k3 premium network, 1 client is joined to the domain and can attach network drives, browse the internet etc.. So no issues with outgoing conections. However we can't connect to this machine (even internally). We can't RDP into the machine (although the Remote is set up correctly), We can't ping the device, but the device can ping out to other devices. The machine i question has a fixed ip address, has the ICS Firewall disabled (turned off). When he does a netstat-a there are listening ports (3389 ex). I checked for stopped services. They run trend micro client server and this device shows up offline (thought this might be a symptom of the problem),. Now both trend services are in automatic status but are not running. I am wondering if this is related to the problem. No problem connecting to other machines where Trend is running. This is a remote user but I am gonna have him check his logs to get any trend micro messages out of there.. Any ideas on this. Thanks in advance..
