Power Surge !

[klingklang]

Morning All. Come into school this am to be told " the lights dipped yesterday i think we've had a power surge"
Now i have half a dozen pc' s which wont connect their profiles and log onto the domain.
Can someone give me some pointers thanks

Do you have a ups?

Is it manageable? as this should tell you in its logs if there was a surge or not.

Can you login locally and check they can see the domain/ping servers etc? Are they all in the same location?

Could be a switch is playing up after the surge.

yeah i'd be looking at the switches they are connected to, its possible that the surge tripped a circuit breaker powering the switches

Thanks for reply,
There is a ups on the server which it didnt affect . Ive 4 PC'S IN ONE class connected via a switch 1 connects ok 3 dont .Then ive 2 other classes with similar issues .
Ive replaced switches . Im now trying to find out local login etc as no one seems to know anything !

Technically a brown out :-P
Local login can be reset if need be.

Thanks to all who replied . Issue now resolved, I pulled the mains out from the affected pc's removed patch cable and unplugged switches for an hour reconnected and everything now ok ...
Time for a cup of tea

Doesn't that come under the category "Have you turned it off and on again"?

Would have been the first thing i would have done ( disconnect untill MB power light goes out), and also turning the switches on and off again

My old work had a server that when a brownout occered overnight and the ups died would require me turning it on and off again for about 20 mins untill i gave up, had a cup of coffee and it would then turn back on.
