Greetings, I'm running Vista Business on an Active Directory Domain. The Network List Manager service has created a second network for the domain I connect to instead of using the one which was setup with the OS install. This becomes a problem since the "Domain Type" property of the network is set to NLM_DOMAIN_TYPE_DOMAIN_NETWORK instead of NLM_DOMAIN_TYPE_DOMAIN_AUTHENTICATED. This causes the network to appear unauthenticated and the machine cannot be browsed via SMB. I cannot find any information in the MSDN docs (http://msdn.microsoft.com/en-us/library/aa370803(VS.85).aspx) about the algorithm or heuristics used to create new networks and assign them properties, and so it becomes quite difficult to diagnose this. What causes this? How can I change the "Domain Type" ofthe newly created network, or how can I get NLA or NLM to pick the correct one? Thanks!

Hi, Regarding the programming issues, I suggest submitting them to our MSDN forum. The support professionals at MSDN forum are better equipped to assist you.

Greetings, Joson, Thanks for the reply. Please note that I'm not attempting to do programming involving the Network List Manager. I am trying to diagnose a network problem in Vista. However, I am using the provided API to troubleshoot, since it gives much more detailed information about the state of the problem. Perhaps restating my problem would help.I have a domain network. My Vista x64 Business installation has a network location associated with this domain. However, it appears that a second, non-domain network location was created for this domain network, but is listed as "Unauthenticated." Vista seems to prefer this network location when I connect, and now file sharing is not working. The "Unauthenticated" state and the desired "Domain" state correspond to values in the Network List ManagerAPI, which I used to browse the network locations, and which I described in my first posting. My questions are: why does a new, unauthenticated network get created, and how to I get Vista to choose the correct, domain network location?
