if you can't login into the database on the standalone pc, add a (local) nav user using this sql script:
USE [YourDatabase]
DECLARE @USERSID uniqueidentifier, @WINDOWSSID nvarchar(119), @USERNAME
nvarchar(50)
SET @USERNAME = 'Domain\user' -- your local pc user e.g. pc-name\youruser
SET @USERSID = newid()
SET @WINDOWSSID = 'Your SID'
INSERT INTO [dbo].[User]
([User Security ID],[User Name],[Full Name],[State],[Expiry Date],
[Windows Security ID],[Change Password],[License Type],
[Authentication Email])
VALUES
(@USERSID,@USERNAME,'',0,'1753-01-01 00:00:00.000',@WINDOWSSID,0,0,'')
INSERT INTO [dbo].[User Property]
([User Security ID],[Password],[Name Identifier],[Authentication Key],
[WebServices Key],[WebServices Key Expiry Date],[Authentication Object ID])
VALUES
(@USERSID,'','','','','1753-01-01 00:00:00.000','')
INSERT INTO [dbo].[Access Control]
([User Security ID],[Role ID],[Company Name])
VALUES
(@USERSID,'SUPER','')
GO
to get your windows sid, start command shell and run:
wmic useraccount where name='your-username' get sid
