Hi Adrian,

Thanks for your interest in the NCBO UMLS prototype Web services.  Below are
the instructions for accessing the services, once you have an active UMLS
code from NLM.  Note that this is still a prototype and could be down at
various times.   

1) - See if this resolves to a
default page.  The page should indicate  "NetKernel Running Successfully".

services have been accessed successfully by external parties.

This URL should redirect you to a "Welcome to the National Center for
Biomedical Ontology (NCBO)!" page.  Enter your license code in the field and
then retry clicking on the URL.  I hope this helps.

Best regards,
