You want to know why TMES clients cannot register to the server when using Windows account authentication with SQL server.
The root cause of this is that the ESClient cannot register to the server because the IIS (Fast channel) cannot access the SQL server using a Windows account.
As a workaround, do the following:
Add the domain account to the Administrator's Group.
Make sure the domain account contains the "Log on as a service" and "Log on as a batch job" user rights.
To add the "Log on as a service" right to an account on your local computer:
- Open Local Security Policy.
- In the console tree, double-click Local Policies, and then click User Rights Assignments.
- In the details pane, double-click Log on as a service.
- Click Add User or Group then add the appropriate account to the list of accounts that possess the Log on as a service right.
Make sure the SQL Server has the domain account and contains the dbcreator and db_owner database roles.
- On the SQL ServerManagement Studio, select the domain account. The login Properties window appears.
On the Select a page pane, choose Server roles.
Tick the checkbox before dbcreator. Make sure the dbcreator and public (default) are selected. Tick the checkbox before db_owner if this role is included in your SQL server version.
The checkboxes selected in this example are dbcreator , public(default).
