Prepare NAV Server Environment

Step 1: Run the NAS installer from the Microsoft Dynamics NAV installation disk (located in the NAS directory) on the production server:

 
Installing NAS 

Step 2: Select 'Typical setup' and finish the installation (leave the check box Start Microsoft Dynamics NAV Application service during the last step unchecked). This will create two windows services; one for native data stores and one for SQL server data stores. By default, the Network service is set as the Log On As user, meaning that the service will run on this account.

Step 3: Go to 'Start menu -> Control Panel -> Administrative Tools -> Services' and locate 'Microsoft Dynamics Application Server' (either native or SQL):

Step 4: Right click on 'Microsoft Dynamics Application Server', go to the 'Log On' tab and select 'This account' option. Enter the credentials for the earlier created SC_Nasuser that will be used. This is needed since you do not want to give the Network service user the Super role in the Microsoft Dynamics NAV administration:

Step 5: Open the 'Recovery' tab and select 'Restart the service' for the options 'First failure', 'Second failure' and 'Subsequent failures'. This makes sure that the NAS service will be restarted when the connection to Microsoft Dynamics NAV has been lost:

Step 6: Click the 'Apply' button at the bottom right and click 'OK'.

Step 7: Grant SC_Nasuser the access to the NAV database:

• Open the Microsoft Dynamics NAV client and connect to the NAV administration with credentials that have enough rights to allow access to other users (must have 'Super' or 'Security' role). Ask your system administrator if you do not have access yourself;
• Go to 'Tools > Security > Windows' logins and type the SC_Nasuser account (with the domain name!) in an empty row;
• Click the 'Roles' button at the bottom, lookup the Super role and select it:

• Close the windows to complete the step.
