  • 0

I have a Web Handler that I’m using to read a file and then stream it out to the client. This works fine if i use the file path on the local drive:
D:\Path\To\My\File.flv

If I use a sharename, however:
\ServerName\ShareName\File.flv

I get a “Logon failure: unknown user name or bad password.”

The share is open to everyone, full control.

I have impersonation enabled and have the following in my handler:

context.Response.Write("Context User: " + ((WindowsIdentity)context.User.Identity).Name + "<br />");
context.Response.Write("Windows Identity: " + WindowsIdentity.GetCurrent().Name + "<br />");

When I configure the IIS application to run as with anonymous access using a specific account, I get the following

Context User:
Windows Identity: SpecificAccount

When I configure IIS to not use anonymous access, but use windows authentication, I get

Context User: MyAccount
Windows Identity: MyAccount

It does not change the error message for the share vs nonshare.

I find this webpage regarding Web Handlers and impersonation:
http://weblogs.asp.net/drnetjes/archive/2005/06/06/410508.aspx

but, I’m not exactly sure how to implement that, or, if it would even solve the issue.

Any ideas?

    Gaah… I hate answering my own questions, but here’s what the problem was:

    The share and file permissions were set properly. This is an old windows 2003 machine and when I use a new application pool (which I did with this particular application), I always have a problem with permissions.

    The solutions was (facepalm) reboot the server.

    I’m sorry for all the braincells that the 60 some odd people wasted on this.

    Thanks again for all your help.

    Stupid IIS… Stupid Windows 2003… must rebuild server someday
