i had a probelm similar to the ones you guys are listing, more a combination thereof. basically my IP had changed on my PC, with no physical changes to the network. none on the network had any access to the internet however. basically, all i did was. shutdown everything, starting with the PCs and working my way up: switches, router, modem. and then waited for about 15 mins and plugged it all back in in reverse order. modem, 2mins then router, 2 mins, then switches, 2 mins then PCs and laptops. now it works fine. its a wired network by the way.

antivirus Q: any problems w/McAfee
Rebooting is effective but not particularly efficient if it happens much...hopefully, Dragon, you don't have a recurring problem and won't be forced to do further troubleshooting (I know it would bug me as to exactly what happened).
Q: Seems some don't mind NAV Corp ed, but I just switched to ZA Security Suite, which I believe uses McAfee's antivirus engine...are there any problems anyone's aware of with this solution? It seems faster and simpler than NAV's solution.
PS as an independent, all I need is to protect a peer-to-peer plus a server or two behind a home router...Corp software not an option, nor desired.

Dragon, sometimes IP configurations can change if a certain system isn't powered on when others are. The reason is because one system stores all the information about a network and workgroups and keeps a table of what systems have what IPs. If that system isn't on when another boots up, the other system may set its own IP at the very initial IP of the set IP range. If you need to avoid this, disable DHCP and configure the IP of each system individually and manually. They will not change again, unless you change them.
Simulaire, make sure the router is a NAT (preferably with SPI). NAT is the single biggest security enhancement for the consumer market.

Have you ever seen a SOHO/retail router that /didn't/ use NAT (PAT, if you want to get more technical)?

Yes, of course the router has NAT (and SPI)...but that is only one level of protection, and not foolproof. You didn't mention:
- only run day-to-day as limited user when connected to (W)LAN
- don't share any folders except carefully designated ones w/permissions thoughtfully set
- good firewall
- good antivirus
- keep up on your patches
- try to avoid software with consistently major security problems (e.g., Firefox has worked quite well for me in place of IE)
I'm sure many of you out there have several more sophisticated approaches but for a small operator with no high-profile web presence, I've yet to have a security breach in 5 years of static ip broadband connection (knock on wood, it could happen anytime.)
Still asking 'though...any feedback on ZA Sec Suite antivirus?

Avoid ZA Security Suite. They use Norton technology. McAfee and Panda do much better.

Incorrect, both you and I! I bothered to track down the facts this time:
According to ZA's own site, they use Computer Associates Vet Antivirus technology.

You're absolutely right. For some reason I was thinking CA owned Symantec rather than Innoculate IT. damn....

The solution might be very simple (as on my PC): Go to services and look for the DHCP service. Some applications might disable this service. I suspect NetSwitcher II might do this for example.
