Did you verify this, or are you saying that from the 1 static IP being introduced.
The computer that was introduced, was it an old server ?
From my experience, it almost sounds like you plugged in a second router to your network.
Are you sure that old computer wasnt a dhcp server with services running ?
Sorry for your troubles, and it would be interesting to know the end result and root cause of all stations having ip conflict.
I know what it might sound like, but it was a standard desktop PC. It had a static IP set that another standard desktop PC had via DHCP. It brought down the entire office.
I know. As a professional with over 20+ years experience, CCNP/MCSE I have never seen this, but then again, I have never used ESET before. I am just wondering if there is a way to disable this behaviour so it won't happen again.
