I have a client who runs a SBS 2008 network of 8 PCs.
Every few weeks they will suffer a lengthy overnight power cut which resets the 2Wire router back to the factory defaults.
Over the phone I take them through the routine of resetting this back up so they have Internet. The Netgear FVS318 which sits between the 2Wire and a Netgear switch has to be rebooted as it picks up the Internet settings from the 2Wire.
Normally after this 10 minute exercise everthing is ok, but not this morning.
The 2Wire is working fine, i.e. Internet connections ok, but the Netgear firewall isn't. Looking at it's configuration everything looks ok, but it is responsible for port forwarding for SMTP, Intranet, connecting iPhones to the Exchange Server and remote connections to the server and a couple of PCs - none of which are working.
We've rebooted the 2Wire followed by the Netgear twice, but still no luck.
