The Network Solutions Registry identified a problem with one of its generic Top Level Domain servers (a.gTLD) that caused negative responses to some DNS lookups for the com zone only between 00:30 and 9:30 EDT on Thursday, 6/22/2000. Although the problem has been resolved, DNS name servers with MAX-NCACHE-TTL parameter set to anything other than the default value may need to have named restarted to correct any possible negative responses to valid domain names.
