503 Service Unavailable

User reported that SharePoint is not sending out alerts, and the alert configurations within SharePoint appear to be correct. When I try to bring up SharePoint Central Administration, I get the lovely 503 Service Unavailable banner. Some of my clients live and die by these SharePoint alerts, so getting them back up is critical. Not to mention that if something is causing the Central Administration to not come up, what else is going on?
When in IIS Manager, I noticed that the SharePoint Central Administration V4 Application Pool was stopped. Naturally I tried to start it, but when you go to the Administration site, you continue to get the 503 error and the service immediately stops. In the System logs, I received 2 warnings and 1 error.
In the System logs, I received 2 warnings and 1 error.
“The identity of application pool SharePoint Central Administration v4 is invalid. The user name or password that is specified for the identity may be incorrect, or the user may not have batch logon rights. If the identity is not corrected, the application pool will be disabled when the application pool receives its first request. If batch logon rights are causing the problem, the identity in the IIS configuration store must be changed after rights have been granted before Windows Process Activation Service (WAS) can retry the logon. If the identity remains invalid after the first request for the application pool is processed, the application pool will be disabled. The data field contains the error number.”
“Application pool SharePoint Central Administration v4 has been disabled. Windows Process Activation Service (WAS) did not create a worker process to serve the application pool because the application pool identity is invalid.”
“Application pool SharePoint Central Administration v4 has been disabled. Windows Process Activation Service (WAS) encountered a failure when it started a worker process to serve the application pool.”
Seeing that the "user name or password that is specified for the identity may be incorrect" lead me to correct conclusion of the password used to start the application pool was expired. In the IIS Application Pool, go to the Advanced Settings for the SharePoint Central Administration V4. Under the Process Model, you will see Identity. This is where you would find the name for the account that is used for this process. Locate this account in Active Directory and change the account password. Then the password needs to be changed for this account in the IIS Application Pool by clicking the […] and by clicking Set to enter in the new password for the user.
