Domino Web Access UI Problem

While accessing through domino web access, The view is not actual DWA like and shows like webmail (or having template like mail6.nsf)…Users Database template is iNotes6.nsf, I hvae run some commands on database like updall, fixup, compact but no result found…

If I assign this database in other DWA user’s document its working fine and if other’s database is assign in this user’s document it again not working in actual view…

If i change the name of the user (ie. from “Prayut Kansara” to “Prayut V kansara” or “Prayut KansaraV”) its again working fine and if rollback again to same name, the problem is starting again…

It is happning in only 3 to 4 users out of 400 users…

Plz help me in this matter, it is some what critical for me…
