The comforting myth that Y2K problems will not affect networking has taken a further blow as a result of a warning issued by ISP, Internet Network Services (INS).
Unless network managers work with their service providers to update a widely used piece of DNS software they will be faced with myriad intractable failures.
Richard Almeida, technical director at INS, said that the older versions of Bind need to be updated or else domain name server (DNS) changes will not go through, making it difficult to diagnose problems.
Tim Challenor, managing director of INS, claimed that many ISPs have failed to sort out the compliance of their network.
"The DNS serial number is the key to the problem, as many dates only use six digits to represent the year in a byte with eight digits, the other two digits being used to represent a negative or positive number. This means that in 2000 several years will disappear, as they will no longer exist," explained Almeida.
Paul Offord, managing director of consultants Advance Seven, said: "If the DNS serial number isn't incremented correctly, changes to name address mappings won't be propagated. Ultimately this will lead to users being unable to connect."
"If you don't do something it will definitely screw it up," he added.
