Unwanted Netbios Traffic in SAP ERP/SRM System
we have a SAP ERP System running on EHP 7 with an SRM 7 SP2 Installation running on the same system. We do not use any Portal but use NWBC functionallity with IE and Chrome over HTTP. This is a 3 - System (DEV, TEST, PROD) Installation.
We have unwanted UDP Port 137 Traffic from of the Production System popping up in the firewall log.
The firewall log shows that this happens twice within one or two seconds and repeats again after 15 seconds.
Does anyone know wich process or service could cause this traffic? Anyone any idea where I have to look at to find the reason for this?
The IT Guys at our customer are getting mad because they arent able to filter this.
I would be very thankful for any hint
