Have had Sophos XG310 firewall up and running for a year and a half. Yesterday after installing Windows updates and a server reboot we started getting thousands of DCOM errors.
DCOM was unable to communicate with the computer X.X.X.X using any of the configured protocols; requested by PID 6bc (C:\Program Files (x86)\Sophos\Sophos Transparent Authentication Suite\stas.exe).
Some of the errors are on devices such as printers within the monitored network, but others such as above are not in the monitored network and they are not in any way attempting to authenticate with the domain as they are VoIP phones.
Anyone have any idea why this would suddenly start occurring AND how to get it to stop?
