+2  Q: 

How can I tell what type of authentication a server is using?

I have to access a web server at http://someserver and it requires some authentication. How can I tell if it is using NTLM, Kerberos or whatever it may be?

+4  A: 

Use a tool like Fiddler to look at the response headers. The server will send back some "WWW-Authenticate" headers that list the different security protocols that are supported.

Fiddler will also tell you if you're using NTLM vs Kerberos by parsing the www-authenticate header.
