Hi I know this issue has raised its head before i have tried the solutions... I have an issue where on a private network no firewall and a basic unmanaged network switch i am getting the DDF failure error. the 750 is as follows
Model NetBotz 750
DCE is running 7.8.1
I have the same issue on various sites.
When the 750 was running 5.2.0 there was no issue but upgraded and now have the problems.
