hi,

a server is constantly trying to access address 1.1.1.1 over udp/137. Could not figure out why. Does someone have an idea?

Thanks in advance.

UDP port 137 is used for Microsoft NetBIOS Name Service. Windows boxes are fairly chatty on UPD/137. Maybe check what WINS server is defined under the TCP/IP properties for that NIC.
