I have a windows 2003 R2 server that I am using in the DMZ as a webserver. This server is not part of a my internal domain and the only communication that it will have with any internal services is via webservices. My questions is can I disable the LM, NTLM and NTLMv2 completely or will that prevent IIS from working properly?

Hi, As this issue is related to IIS, I suggest discussing it in our IIS forum: http://forums.iis.net/ Tim Quan
