Try getting to PC Anywhere from other LANs, run basic ping, telnet and ftp tests, and confirm that the Network Access Rules configured correctly. Block Untrusted chat software using Network Access Rules.

Make sure you update your Symantec product, recent exploits have been found and causing problems all across the net. Let me fill you in:

I think the computer is being DoS'ed

If you can find out who's scanning you constantly you could report the person(s) to their ISP.
