Server Application Error

The server failed to load application '/LM/W3SVC/1/Root/'. The error was 'The server process could not be started because the configured identity is incorrect. Check the username and password'


there are 2 ways to resolve the issue.

1)

Give "Logon as a batch job" rights to the IWAM_MACHINENAME and IUSR_MACHINENAME accounts. To do this, follow these steps: 1. On the Administrative Tools menu, expand Local Security Policies.
2. Select User Rights Assignment.
3. Select the IWAM_MACHINENAME and IUSR_MACHINENAME accounts.NOTE: If domain level policy settings are defined, they override local policy settings. Make sure that the Effective Policy Setting is also selected (this setting is dimmed). Contact your domain administrator if this setting is not selected


2 ) Resetting the application in IIS

Go to Sites properties and on home directory tab, set app process from high to low and click apply, then set back to high and click apply


All set.
