Internet locked out a few times each day

I am encountering a problem with my main Win XP Pro system which occurs a few times each day.  Without any use, I will return to find Internet access dropped.

The only Event Viewer entries I  see are these:

The server {F3A614DC-ABE0-11D2-A441-00C04F795683} did not register with DCOM within the required timeout.

I also see a trio of meesages saying "The LiveUpdate service was successfully sent a start control." followed by "The LiveUpdate service entered the running state." followed by "The LiveUpdate service entered the stopped state.".   These repeat for an hour or more.  I suspect Norton so I'll dis

But I also wonder after reading messages if my WINS setup (which I do not specifically have) may play into this.

Please advise.

Who is Participating?
it has been my experience that
1. there will be weird logging of dcom stuff
2. the people who fully understand dcom are the ones useing it for there benefit, the rest of us in the dark.
3. if you stop the services, you will find that everything stays running happily (unless a 3rd party application uses it, in which case it would already be unstable and spewing it's own entries, ) you will get more spew in the log.

however I've been wrong before.
during outages can you ping your DNS server?  are you on a domain?
can you ping your ISP's DNS servers during outages
can you ping other hosts (external )durning outage?
I suspect it is either DNS related, or spyware.

Thx for fast turnaround and support.  I am upping the points becuase this is now a business problem for me (MOnday and staff coming back to office).

Not on a domain ... setup as a workgroup with about 6 PCs (2 desktops, 4 laptops) all running Win XP Pro.
I have 2 DNS servers setup up in TCP/IP settings and expect they will respond to a ping but will try next time before I reboot.

The DCOM message just was logged again and I now am locked out from Internet access.  I do not know what server this message is referencing.  I am running an Apache server with mySQL and also an FTP service.  

I am not in office but can remotely connect to the server when this occurs so I have enough connection into the system to do a Windows task manager and select Restart.

PLEASE ADVISE FAST!  I am rebooting every few hours.

I have cleared all spyware tests and found nothing.

I am running a Sokkit stack including Apache and MySQL for past 6 weeks and usually can see that the web is down which alerts me to my PC not servicing.  The Apache keeps running but my Sokkit control panel which is not a service (runs under my login) fails and I think that is due to same problem that keeps IE from working.
so no 'server' but a firewall/gateway box (linksys or similar) tell us about the DNS settings and be willing to change them to ISP provided .

I just added a third DNS server to my TCP/IP.  The other two are provided by my office complex.
I use a Linksys router.

I just read a lot about dcomcnfg.exe and ran it.  When I navigated down through Console Root > Component Services > Computer > My Computer > DCOM Config, it prompted me for about 6 CLSID that had the named value AppID but is not recorded under \\HKEY_CLASSES_Root\AppID.  It then asks "Do you want to record it?".  I clicked YES on each one and it then displayed a long icon list.

But when I run dcomcnfg again, same prompts.  I wonder if Norton is blocking the registry from updating?  I have NO idea what this DCOMregistering is all about.
DCom reg events are common, Distributed COM is programming stuff allowing software to access OS shared code and it usually does not indicate anthing wrong.  I see them on happy systems.

Are you saying that this error/warning is acceptable and not the cause of any problem?

Here are the two entries I got before the system locked up earlier this afternoon.
