Dear All,
My problems mentioned in my previous two topics "Employee Portal ..How To " and "Employee Portal OS=Domain controller?" is solved now.
I found that NEP_User has to be defined for the NAS logon only. There is no other role of NEP_User exists except its definition in the NAS Logon.
Also I was not able to See the webpage was becuase in the IIS Manager->Default Website->Directory Services->Edit Authentication and acess control there has to be check mark in the field Integrated Windows Authentication. After checking this everything starts doing correctly.
Thanks to all for their copperation.
By the way I am now installing the Employee Portal on the diferrent Machine and I am getting some new errors
