Quick Reminder about DNS & DHCP
Hi All,
I have recently had an issue with a clients ADSL line, which decided to be a right pain, it usually had around 4mbps, then one week it decided to drop down to dial-up speed. It was absolutely awful, very difficult to do anything, when they have an office with 30 workstations chugging away.
We raised a ticket with the ISP in question and long-story short, we had to get a new line installed, it turns out the line was damaged somewhere between the building and the exchange.
So now that we were presented with a new IP range, we had to reset lots of devices, printers, scanners, access points and of course the servers, proxy server and static-ip PC’s.
All the DHCP PC’s would automatically get the new IP once we had change the scope on the DHCP server, so we thought.
But it didn’t and the reason is, that you must remember to restart both the DNS and DHCP services otherwise the Microsoft Server 2008 will not use the new scope!

Been bit by that one before. Another one to watch out for in the dhcp/dns world is dns scavenging. If you have a network with a lot of wireless laptops coming and going you get stale records.
The scavenging functions in Windows (surprisingly) take quite a bit of studying to get your head around.
