  • Article

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 runnning, and any include files must be configured correctly.

Resolve

Check file access

Possible resolutions include the following:

  • If W3SVC was unable to read a file, verify that the file indicated in the error message exists and that W3SVC has permissions to the file.
  • If the file was too big, reduce its size.
  • The event log message may contain an error number that can provide more information about the issue. To do this, see the following steps.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.
