3. Summary of Client’s Responsibilities
3.1 The recommendations for University systems using this service are given at http://www.oucs.ox.ac.uk/network/wins. In particular, as the NetBIOS namespace is flat, unlike the DNS namespace, there is potential for name clashes. Clients should use the documented naming conventions to minimise the likelihood of clashes occurring.
3.2 In order to maintain service throughout routine operations such as patching of servers, clients need to be configured with the addresses of both WINS servers.
4. Premium Services
