On February 8, ITS Identity and Access Management (IAM) will disable the ITS Windows Internet Name Service (WINS). If you have Samba file servers that are more than about 10 years old, you may want to verify your configurations.
WINS is a now-deprecated predecessor to Domain Name Service (DNS) and was necessary for Windows NT, Windows 98, and early versions of Samba. DNS replaces WINS in modern versions of Windows as the method for mapping hostnames to network addresses.
