Rumor has it that if you used netsol's web site to search for a potential domain name, that they "bought" the domain and held it for 5 days, in case you really did want the domain. They've taken heat from media and now ICANN about this policy. They claim they are protecting their potential customer from domain squatters.
Verify that netsol is the owner of the web site, by doing a whois of the domain name in question. If the domain is owned by someone else, they could have simply enabled netsol parking, which means they have no webhost, but want a generic page for their domain.
