Number |
Description |
|---|---|
0x80070057 |
The value specified for Category is invalid or Path is a zero-length string or NULL. |
0xC00D0036L |
Name is already being used by another publishing point. |
0xC00D1455L |

Remarks
The name of the publishing point must be unique. You can indicate the home publishing point by specifying only the forward slash character (/). There can be only one home publishing point, and it can be either a broadcast or on-demand publishing point. A home publishing point is not mandatory, but it enables clients to connect using the shorter URL formats such as and .protocol://server_nameprotocol://server_name/file_name
Any other publishing point names must not contain a leading or trailing /, but a / character is permitted in the middle of a name. The following characters are not permitted:
< > \ ? % & ' # { } | ^ [ ] `
White spaces are permitted in the name, but the server will strip leading and trailing white spaces.
The path must start with an appropriate prefix to indicate the data source plug-in to use. The following table illustrates valid paths.
