Workflow Manager may not be able to send emails, run scripts, or access file system templates if system settings are not configured properly.

Symptoms

AMS Web Application Emailer Exception:AMSTemplateEmailer.SendEmail()

Exception information:
Type: System.Exception
Source: AMSBusinessLayer
Message: AMS failed to Impersonate as User 'AMS_SYSTEM' in Domain 'DOMAIN' Win32 Error Code is '####'

Cause

• A win32 error code of 1326 indicates "Logon failure: unknown user name or bad password".
• The account specified in System Settings may not have been granted the local policy of 'Logon Locally', which is required for ASP .NET User impersonation.
• In some situations, an invalid recipient can cause no notifications to be sent. In this case, the invalid user will be listed in the exception message, and no other recipients will receive an email since the entire email was not sent.
• Some customers have reported that Anti-malware software will block any SMTP traffic coming from the IIS worker process.

Resolution

a. Run the command gpedit.msc

b. Navigate to Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> User Rights Assignments -> Log on locally.

c. Verify that the user or group has been granted this effective permission. If not, make certain that the account used for user impersonation has been added to this permission.
