When I've seen this error it's usually haven't had anything directly
with NTLM or SPNEGO authentication. In fact getting there, to get a
500, rather than a 401, has indicated that my client and IIS had
finished their authentication, and the problem occured between IIS and
our own ISAPI extension.

Do you use any ISAPI extensions on the IIS in question?
