Verify :
To perform this procedure, you must have membership inAdministrators, or you must have been delegated the appropriate authority.
To verify the state in which a service is operating:
1.Click theStart button,Run, then typecmd to open a command prompt.
2.Typesc interrogate service_name (where service_name is the name of the service) at the command prompt to update the status of that service in Service Control Manager.
3.Type sc qc service_name at the command prompt to display the configuration status of the service.
4.Typesc queryex service_name at the command prompt to display the extended status of the service. This command will provide the following information about a service: SERVICE_NAME (the service's registry subkey name), TYPE (the type of service, for example, shared process, interactive), STATE (for example, running, paused, and the states that are not available), WIN32_EXIT_CODE (the Windows exit error code), SERVICE_EXIT_CODE (the service exit code), CHECKPOINT, WAIT_HINT (the time period the SCM waits before reporting a service failure), PID (ID of the process running the service), and FLAGS. If the service was started successfully, the WIN32_EXIT_CODE field should contain a zero (0). If the service failed to start when an attempt was made, this field should contain an exit code provided by the service when it could not start.
5.Typenet helpmsg exit_code (where exit_code is the 4 digit number of the error code) at the command prompt to display the meaning of the exit code.

According to News Group
"Event 7011
Description:
"Timeout (30000 milliseconds) waiting for a transaction response from the MSExchangeIS service. Data:"
This can happen if any SMTP sink, either from Microsoft of third party is acting weird. What third party software, such as Anti-virus, Anti-spam do have installed on the machine? Try uninstalling them and see if that fixes the problem.

A lot of software, both from MS and third party, run in IISs (inetinfo.exe) memory space. Although this is very efficient mechanism as far as response time goes, it creates a big dependency tree. If any one of this dependent corrupts the memory, it brings down all other services along with it. Following software run in inetinfo.exe

IIS Admin
Most of Exchange services
SMTP
NNTP
FTP
Any Anti-Virus, Anti-Spam written as Sink"
