    I think you are installing NAV using a user who is not a trusted login (Windows Login): please retry using a valid Windows user.

    thanks for answer

    But I use for installing MS Dynamics Server & the NAV SQL Data server the same service account (domain SERV account ) for installations in both machine .

    But for login to each machine using domain user account is that you mean cause such error ?
