On a Windows 2008 server with IIS 7, I installed the SMTP service (configured through IIS 6.0 Manager) for an application to be able to send e-mail. At first, the SMTP service started without any problem. But the last two times the server has been rebooted, the SMTP service has failed to start, with event ID 7023 &quot;The Simple Mail Transfer Protocol (SMTP) service terminated with the following error: Not enough resources are available to complete this operation.&quot; (I am able to manually start the SMTP service, though.)

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.
