Change "Unidentified Network" network location from public to private

Q: One of our Windows 7 is located in our SAN VLAN and doesn't need to access The internet so that it doesn't setup default gateway. I have enabled remote desktop, but can't access it from other computer in the same subnet using RDP. I found the firewall disabled remote desktop on Public location (note: remote desktop is enabled in the private network). I must enable the remote desktop in the public location to be able to access it remotely. That is OK. My question are:

1. Why the LAN display "Unidentified Network"? It is because it doesn't have default gateway?
2. Do you know a way to change the "Unidentified Network" network location from the Public to Private? It doesn't give you the option to make the change when it is "Unidentified Network".

Thank you.

A1. Why the LAN display "Unidentified Network"? It is because it doesn't have default gateway?

==================

Yes, you are right. If the connection doesn’t have a default gateway, the Network Location Awareness service consider the network as Unidentified.

The Network Lists service (netprofm) works with the Network Location Awareness service (nlasvc) to identify networks and find the associated saved settings for the network, if any. The NLA service will use a Default Gateway or SSID to identify a network, so if the NIC has neither a Default Gateway or associated SSID, then NLA will determine that the network is Unidentified, and will automatically use the Public Firewall profile, which is the most restrictive and secure.

The two articles below would help you understand NLA better.

Why is my network detected as “unknown” by Windows Vista or Windows Server 2008?

A2. Do you know a way to change the "Unidentified Network" network location from the Public to Private? It doesn't give you the option to make the change when it is "Unidentified Network".

==================

Yes, we can change the network location type from Public to Private for Unidentified network from Local Security Policy. Please follow these steps:

1. Click on Start->Control Panel->Administrative Tools->Local Security Policy

2. Expand to Security Settings->Network List Manager Policies



3. On the right pane, double click Unidentified Networks and we can change the type from “Not configured” to “Private”



Q2; Adding default gateway doesn't make any different. However, change “Not configured” to “Private” is the answer I am looking for. Thank you very much.

A3: After adding the default gateway, you should restart the compuer or at least, restart the NLA service. This may help the computer re-detect the network. I am still glad to hear that the information on how to change the network location type is helpful to you.
