Posted on by Sumit khanduri 1,300

There are 6 service on each i have to give account name, my question is do i have to create different accounts for each service if it so, what rights i have to give to each account.

    Hi Sumit,

    it is not a "must". you can use accounts provided by the user , it is just recommended you create specific accounts for the sake of security. you may also run into trouble if you have a distributed  server scenario on a complex network

    you can use accounts like 'NT AUTHORITY\NETWORK SERVICE' but is not good practice

    more details:

    be aware that if you chose an account while installing, you can still change it after. this will be under the "services" on your server

    Agree with Bruno.

    Just one more thing if you use Domain Account as dedicated account, you need to manage your own password, so better to set password never expires otherwise after expired (for example for every 3 months then expired), the service will be stopped and you need to manually change the log on user password.

    Hope this helps!

    Thanks.

    A couple of quick additional points:
    - NEVER use an account for the services that will or might be added as a user in CRM in the future

    - therefore, never use the account you are using to install CRM, since that will always be added as the first user in your new Organization.

    one last question

    Does the domain service account needs to be local admin?

    Here is the post from microsoft that provides minimum permission required for each service account.

    http://technet.microsoft.com/en-us/library/hh699825.aspx

    * It always better to start right rather thinking of changing  service accounts later later.

    * Microsoft recommends to use different domain user accounts for each service accounts in order to avoid security issues that may arise.

    • Read permission to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM subkey in the Windows registry.

    • The service account may need an SPN for the URL used to access the website that is associated with it. To set the SPN for the Sandbox Processing Service account, run the following command at a command prompt on the computer where the service is running.

    IIS Application Pool identities running under Kernel-Mode authentication and SPNs

    By default, IIS 7.0 and IIS 7.5 websites are configured to use Kernel-Mode authentication. When you run the Microsoft Dynamics CRM website by using Kernel-Mode authentication, you might not need to configure additional service principal names (SPNs) for the CRMAppPool identities.
