We came in this morning and noticed that there was a DNS problem where we could not get to external sites.
Internal DNS settings appear to be working, but we cannot get to any external websites without typing in the IP address.
I'm not aware of any updates that were installed or changes that were made.
We are in a windows environment and have split DNS setup so (under normal circumstances) we can resolve to internal and external ip's.
Where should I start troubleshooting?
