One of the interfaces had the same IP range as my own lan (which I am also monitoring in netxms)
so naturally, this router interface was placed inside my own LAN "group"

Now I have deleted the router from the "entire networK" section, but when I delete the router
from my own LAN "group" it hangs on the "deleting object" screen and eventually it gives the error
"Unable to delete object: Request timed out"

Everything I try to do after this error occurs just hangs. For example when I try to open up the "alarms" screen
it times out, I have to shut down the console, log in again, and then I can work again.

What could be causing this?
