ME020438 - PRB: MailEnable .NET web mail or web admin may return a "Service Unavailable" error


SYMPTOMS

The Windows Event Log or MailEnable Diagnostic Report may report any (or all) of the following errors:

The identity of application pool, 'MailEnableAppPool' is invalid.  If it remains invalid when the first request for the application pool is processed, the application pool will be disabled.

The identity of application pool 'MailEnableAppPool' is invalid, so the World Wide Web Publishing Service cannot create a worker process to serve the application pool.  Therefore, the application pool has been disabled.

A failure was encountered while launching the process serving application pool 'MailEnableAppPool'. The application pool has been disabled.

CAUSE

These errors may be reported by Internet Information Server (IIS) Version 6 if the account identity for the MailEnableAppPool application pool is not valid.

This may occur if the password for the IME_ADMIN account has been recently changed.

RESOLUTION

The solution to this is to reset the password for the IME_ADMIN account to a known password and use the Internet Services Manager MMC (IIS Console) to set the 'Identity' for the MailEnableAppPool application pool.

The alternative is to run the MEInstaller application and execute the options to reconfigure both web administration and web mail. This will prompt for a new password for the IME_ADMIN account, and will reset the identity of the application pool.
