Hi i installed windows server 2008 R2 (on Hyper-V) , but : 1- I can't change Network Location . 2- in change advanced sharing setting , i changed Network Discovery Setting to Turn on network Discovery and save change , but my settings not saved. i tried to apply policies with secpol.msc , but not effected . can you halp me ?

How is the networking configured in the server? What sort of network does this server connect to? Can Windows identify the network? What does it say about it? You cannot change the sharing options if you are not in a private network.Bill

Hi Arad Haghi, Thank you for posting here, In order to enable the Network Discovery settings, you may make sure the following services are enabled and running. - DNS Client - Function Discovery Resource Publication - SSDP Discovery - UPnP Device HostWilson Jia - MSFT

How is the networking configured in the server? What sort of network does this server connect to? Can Windows identify the network? What does it say about it? You cannot change the sharing options if you are not in a private network. Bill Dear Bill Grant According to instruction mentioned in 70-642 book (Configuring windows server 2008 network infrastructure) , i wish to implement relevant scenarios and exercises . For this reason , i installed and implemented two windows server 2008 R2 via Hyper-V . Both server connected to each other via Virtual Network Manager with define a Private Network . one of these servers is equipped with one network adapter and other has two . one of the twin adapters of the latter is disabled . IPv4 and IPv6 are enabled on both adapters and both have static IPv4 and IPv6 address . Network and sharing center shows that my network is an unidentified network and demonstrates my network location as public . no servers can't create network map (because the network is public) . Earlier on windows server 2008 R2 , i was able easily to change network location and enable or disable network discovery on Windows Server 2008 or on Vista , But unfortunately i can't find any option to do so on windows server 2008 R2 or Windows 7 . Best Regards Arad

Hi Arad Haghi, Thank you for posting here, In order to enable the Network Discovery settings, you may make sure the following services are enabled and running. - DNS Client - Function Discovery Resource Publication - SSDP Discovery - UPnP Device Host Wilson Jia - MSFT Dear Wilson Jia Thank you very much for your kind comments and cooperation , now one of my problem is solved after the followings was done by me according to your guidance which was as follows : Function Discovery Resource Publication server status was stopped , and start up type was set to manual . furthermore , SSDP Discovery and UPnP Device Host services were disable . i enabled it and started the above mentioned services . now when choosing change advanced sharing settings and then after turning on network Discovery and saving changes , Network Discovery become enbale . However still somemore questions remain for me and wish to receive your replay and guidance again to these question . 1 - Referring to above subject , Please let me know if network Discovery and associated services is disable by default on windows server 2008 R2 . 2 - How could i change network Location ? RDGS

Hi Arad Haghi, 1. By default, the Function Discovery Resource Publication service is Manual. SSDP and UPnP Discovery service are Disabled. 2. Network location is determined by system. We cannot change it. Whenever theres a network change (say it receives a new IP address or sees a new default gateway or gets a new interface), a service called Network Location Awareness (NLA) detects the change. It builds a network profilewhich includes information about existing interfaces, whether the computer authenticated to a domain controller, the gateways MAC address, and so onand assigns it a GUID. NLA then notifies the firewall and the firewall applies the corresponding policy (theres a policy defined for each of the three profiles). For your reference, here is a good blog which can be helpful for you.

Just have to say thankyou to Arad Haghi, this also fixed my same problem. all working well now

I am having the same problems with R2. I enabled all the services you advised and now network discovery is showing as ON for the Domain, Public and Home or Work but other machines on the domain still CANNOT see this machine. Also, I didn't have to enable these services to get network discovery to work in ANY other version of Windows when connected to a domain. This seems a little long-winded and over-complicated just to get network discovery working. I'm sure there's something simple I'm missing but for the life of me can't figure it out!

thanks, its solve my problem!!! Ricardo de Lima

Hello Arad, You are Champ..... The services you suggested to start this resolved my issue. Thank you so much for you help with explaination.

Hi Arad Haghi, Thank you for posting here, In order to enable the Network Discovery settings, you may make sure the following services are enabled and running. - DNS Client - Function Discovery Resource Publication - SSDP Discovery - UPnP Device Host Wilson Jia - MSFT Yes! now it work.

Perfect! Thanks for posting, was scratching my head for a while there. Just getting into Server 2008 R2 for the 1st time so this has helped a great deal. Kudos, ;) Jason
