In order to perform its activities successfully, the Internet Information Services (IIS) World Wide Web Publishing Service (W3SVC) must be free of any I/O errors involving file access, memory availability, and network connections. In addition, any scripts that are used must be accessible and running, and any include files must be configured correctly.

Check a connection failure

To resolve this connection issue, check the event log message for a specific error number included in the message. This error number will be different from the Event ID. To do this, see the following steps.

Check for a specific error number

To check for a specific error number:

• In the Event Viewer, select the event that you received.

• Click the Details tab, then Friendly View.

• If a specific error number is available, the words Binary data: should appear.

• Below In Words, note the number after the colon.

Find out more about a specific error number

To learn more about a specific error number:

• Download the Err.exe utility from the Microsoft Exchange Server Error Code Look-up page.

• Click Start, All Programs, Accessories, and then Command Prompt.

• At the command prompt, navigate to the directory where you downloaded err.exe. For example, if you downloaded err.exe to C:\Err, type cd C:\Err.

• Type err errornumber to obtain more information about the error. For example, if the specific error number is 80070005, type err 80070005.

• In the example in Step 4, the error resolves to ERROR_ACCESS_DENIED, so your next step would be to check for a permissions issue.
