speckytecky Posted August 31, 2012 Posted August 31, 2012 I've got a little problem! School electrical rewire over the summer but servers were kept live but did not have network access. Part of the rewire included some fibre between two new HP Pro-curve switches. All back on today but initially the DHCP Server was not handing out DNS Addresses. Restart of service fixed that. Currently only local access, router pings ok but refuses to give Internet. Also trying to get the HP switch to talk over fibre to a Cisco switch downstairs is not working despite the supplier telling me the Gbic is correctly configured. Any thoughts please?
cpjitservices Posted August 31, 2012 Posted August 31, 2012 Have you tried other cabling ? - I suppose it could be possible that if you've had an electrical rewire then a cable could have been nipped somewhere ? 1
speckytecky Posted August 31, 2012 Author Posted August 31, 2012 I have not had a chance to delve properly yet but it looks like the actual Network is connecting - the issue seems to be that we can't get the Internet. Having said that there is nothing live on the Network yet other than the second DC and the Mini Mac Server.

SYNACK Posted August 31, 2012 Posted August 31, 2012 (edited) Rebooted the router? Logged into the router directly to see if it gives any clues. Any new routing/ipranges thanks to the new HP switches? Are your default DNS servers up, these should be the DCs and whatever they talk to upstream. tracert to a website nslookup to an external website Edited August 31, 2012 by SYNACK 1
speckytecky Posted September 1, 2012 Author Posted September 1, 2012 Seems to be OK now - looks like it was a combination of DHCP not restarting it'self after it's dormant period then the proxy setting of GP not having been picked up by the DC itself!
twin--turbo Posted September 1, 2012 Posted September 1, 2012 Out of interest, could the servers talk to each other? DC's don't like extended periods when they can't talk to each other. Rob
speckytecky Posted September 1, 2012 Author Posted September 1, 2012 Yet to check that one out - thanks for the heads up Rob. May be back for advice on how to fix if it is the case!
