Unexpected error during AOS installation

[Amiya]

Hi Everyone,

When i am installing the AOS i am getting an unexpected error which is
mentioned below. I am installing AX client, fileserver and AOS in one
server(0150-0426-AD02) and my database is present in another
server(0150-0426-DB07)

=== Setting up Object server ===
Adding account RMDNT\0150-0426-AD02$ as a login in SQL Server
Warning: Setup could not connect the Application Object Server (AOS)
instance to the database because it could not add the AOS account
RMDNT\0150-0426-DB07$ to the database server as a login account. Installation
of the AOS instance was completed, but the AOS instance cannot run without a
connection to the database. You might not have permission to modify security
on the database server. A database administrator can grant permission
manually, and then AOS setup will be complete. For more information, see the
installation log file for the error message returned by the database.

Hi,

sounds like a user rights problem.

Please check that the account you use to install the aos has the following
rights:

Member of the Administrators group on the computer that you are running
Setup on.

Member of the Security Administrators server role on the Microsoft SQL
Server you want to connect to.

Please also take a look at:
