Power cut - no internet for some

[KWestos]

We had a power cut last night. Now some users cannot access the internet (regardless of the machine). All the proxy settings are there, refreshed policy, etc, but still no internet.

Can anyone point me in the right direction

@KWestos:

Daft question I know but in light of the incident it begs to be asked, "Is the proxy server switched on?"

We had a similar problem and the phone line had broke due to the powercut so get BT or who ever to confirm its still working and they can see you switches

On a fluffed machine:

1: check it's ip address.
2: ping your PDC/DNS
3: ping gateway
4: ping Google (should resolve to an ip address and ping away)

any of those fail and you've found your culprit. (unless 2 & 3 block icmp
