The n-tyneside.sch.uk domains have been out of use for many years now. They were hosted by RM on behalf of NTC but we ceased this provision in 2007 on the basis that they were convoluted, most schools prefer a simpler .org.uk domain.
Our team can register .org.uk domains on behalf of schools. Please contact email@example.com for further information.
To register a .sch domain, nominet offer this service now. See this link http://www.nominet.org.uk/uk-domain-names/registering-uk-domain/choosing-domain-name/schools
