Ok, I just did some snooping around about the ports and the services that were mentioned ;)
I am not sure about the system process that are listening to/for udp communication...
However, about the Sygate smc.exe listening to port 1027 - this is for
2 reasons:
1st- smc.exe is a part of the Sygate Secure Enterprise, more specifically the firewall product. This piece of software blocks attacks from Internet-bound viruses and hackers. This program is important for the stable and secure running of your computer and should not be terminated. (quoted from:

2nd - Microsoft operating systems tend to allocate one or more unsuspected, publicly exposed services (probably DCOM, but who knows) among the first handful of ports immediately above the end of the service port range (1024+). (and) The most distressing aspect of this, is that these service ports are wide open to the external Internet. If Microsoft wants to allow DCOM services and clients operating within a single machine to inter-operate, that's fine. But in that case the DCOM service ports should be "locally bound" so that they are not wide open and flapping in the Internet breeze. (from:

Sooo....on Port 1027 having a tool from the firewall snooping/sniffing about is not a terrible thing to have.
Search on Google for the other services and ports and it will give ya Tons of info!
