First of all I hope I did understood your question properly but if you meant that you are not able to double click names.nsf and open it using the DWA( Domino Web Access ) 8 please notice the following :
1- There are two types of DWA8 the files one is the Full version and the second one is the Lite Version and from the name you can know that the Lite version is the one doesn’t put much load on the Network put it has less features than the full one .
2- in order to be able to use DWA8 on a mailbox of a user the template of this mailbox must be ( Mail8.ntf) and the ODS must be 48 but any customized database or a one with no template and names.ntf is a sort of this
3- for some security or consistency purposes I recommend you to open it using the LN Administrator .
My pleasure if this is handy
