Accessing local file server with no internet

    Question

  • Hi,

    Do you know if it is possible to access data from a local file server that is hosted on a DC, if you are local to that DC but have no internet? 

    The reason I ask, is that we have this issue when our sites lose internet; some users at site can access the local file share on the DC, but most cannot.

    We are using server 2012 with a functional level of 2008R2 on our AD.

    Any help appreciated.

     First of all,file server role configure on a DC does not recommended.Maybe that's the main issue.So internet connection doesn't make sense with access local resources.(at same site.)

     So you should migrate file server role on a member DC,you can migrate with robocopy;

  • Accessing a file share (hosted on a DC or not) has nothing to do with internet access.

    Have you configured a proxy server ?  Do you have any exceptions (like local subnets ?)

    Do you have the same issue using the name and the IP address of the DC

    There is no requirement to have internet access but connectivity to your server. Having your DC running as a file server is not a recommended practice for security reasons.

    The reason I ask, is that we have this issue when our sites lose internet; some users at site can access the local file share on the DC, but most cannot.

    It seems that this is more related to a DNS resolution failure. You can use NSlookup to check the DNS resolution. Please also make sure that your clients point to an internal DNS server for DNS resolution.

  • Hi,
    Alternatively, you could also run dcdiag /test:dns command to see if more if more information could be offered for troubleshooting and you could refer to the detail explanation if any error is returned.

  • Thanks all, 

    Most of our File servers are not on the DC, but in a couple of instances they are, so we will need to move them.

    The issue where local users cannot access the local data seems to be DNS as you have stated, I will give this a go and let you know if we find a solution
