Author HTTP 501 - Not Implemented

I am using the HTTP PUT command to upload images to IIS server. Same code
uploading to IIS 5.0 works great, uploading to IIS 6.0 throws error "(501)
Not Implemented". This error code is confirmed in the IIS log file.

Write properties are enabled on the web folder, Read Only property is
disabled on the local directory.

Call is made through c#:
WebClient.UploadData(string address, string method, byte[] data);
-->in this case method = "PUT"

The address, and the method, and the data have been validated against IIS
5.0.

Testing has been done inside the firewall, ISA is out of the equation,
command is going directly to IIS, fails on local machine as well as remote.
Same problem on clean install of Win2K3 w/ IIS 6.0.

I understand that IIS 6.0 installs in a very secure mode, have not found any
doc's specific to this problem.

Does anyone have any ideas?

Many thanks.

This was too obvious to be simple.

Although I had enabled the WebClient "service", I had not gone into the
IIS MMC -->Web Service Extensions
and "Allowed" WebDAV.

Live and learn, I hope this will help someone else.
