The request failed with HTTP status 401: Unauthorized

Hi,

I have a web service on server A, calling the SPFiles.asmx sharepoint
built-in web service on server B, I'm using the getDocument() method
that returns a byte array.

Using Kerberos and impersonation, my web service passes the user's
credentials to the sharepoint box, and all of this is working fine.
However, some of the time, just out of the blue, I get the following
error:

The request failed with HTTP status 401: Unauthorized.
at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(...)

If I try it again, it will work fine for another 5 minutes or so.. I
have hardcoded my credentials and it does the same thing, so I know
there is no problem with passing the proper credentials, but I'm
wondering what's going on on the other end.

Has anyone encountered a similar problem?

Thanks a lot,

sylvain.
