Access denied when Called CreateFile()

When called CreateFile() function it returns an error code 0x5, which means access denied. Can anyone help with this issue?

Note: CreateFile() reads the path of a snapshot, and the file开发者_开发知识库 path is \?\globalroot\device\harddiskvolumeshadowcopy35\program files\common files\microsoft shared\web server extensions\12\admisapi.

thanks very much.

Can you you create that file manually? This is most probably a permission issue.

This means that you don't have enough rights to read from this file. Check the file permissions.

Access denied, where is your application trying to create the file? If its in program files etc, it maybe because its windows 7 and the user cant create it without elevating the permissions first. Also, be sure its creating it where you think it is.
