Hi,
After a recent OS update where the ethernet drivers were updated, we lost
the network configuration for the spectrometer. Just added the IP address,
mask etc back into network and all was good again.
Hope it is that easy for you.

> Subject: [AMMRL] Xenon connection issue
Hi AMMRL group,
I am having an issue with the Xenon software connecting to the EPR.
When opening Xenon I get the error - ERROR (user) in localhost
I have tried different ethernet cables. Tried rebooting the spectrometer,
the computer. The network switch LEDs are blinking, the work station LED's
are blinking. eth0 pings but eth1 does not.
Last week there was a chiller issue which resulted in a very low temp and
sweating on the magnet. I was out of town so a helpful user switched everything
off. The EPR was off for about 5 days.
I don't know if that was the cause of the connection failure.
If anyone has had something similar happen I would appreciate any thoughts.
thanks,
jaya
