The Microsoft® Exchange Server Analyzer Tool queries the Win32_Service Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the Started key for the Simple Mail Transfer Protocol (SMTP) service. A value of False indicates that the SMTP service is not running. A value of True indicates that the SMTP service is running.
The Exchange Server Analyzer also queries the Internet Information Services (IIS) metabase to determine the value for the ServerState property for the SMTP virtual server instance.
The ServerState property presents the current state of the server instance. The state codes, and the corresponding states, are as follows:
| State Code | State |
|---|---|
|
1 |
Starting |
|
2 |
Started |
|
3 |
Stopping |
|
4 |
Stopped |
|
5 |
Pausing |
|
6 |
Paused |
|
7 |
Continuing |
The Exchange Server Analyzer displays a warning if the following conditions are true:
- The SMTP service is running.
- All SMTP virtual server instances on the server are
started.
This warning indicates that, although the SMTP service and SMTP virtual server instances appear to be functional, an issue that requires additional investigation prevents the SMTP ports from responding correctly.
This issue might be caused by the following:
- The SMTP service is in a hung state.
- A firewall or antivirus application is blocking communication
to the SMTP ports.
To address this issue:
- Restart the SMTP service.
- Review the configuration of any firewalls or antivirus
applications with regard to the SMTP ports.
- Review the specific error guidance and links provided by the
Exchange Server Analyzer.
