The name “Domain :1d” could not be registered on the interface with IP address 172.16.4.40. The computer with the IP address 192… did not allow the name to be claimed by this computer.
This is either because the NETBIOS name is already used on the network, or the NETBIOS domain name matches that of a NETBIOS workgroup name.
It’s safe to ignore this error in most cases. If you wish to fix the error, find the computer whose IP address is mentioned in the error and change either it’s name or workgroup (depending where the conflict is). Alternatively, rename the computer with the error (or change its workgroup).
