Just wanted to post and let some of you know that if you recently upgraded some Windows 7 clients to Windows 10 and you're unable to access SMB shares/re-join or join a domain we discovered that the DNS Client service is disabled. We edited the registry to enable that service to start. We confirmed this by looking in Event Viewer at: App and Services Logs -> Microsoft -> Windows -> SMBClient -> Connectivity. There were error events that the server name could not be resolved. Upon checking services the DNS Client was disabled. The key we edited was HKLM -> System -> CurrentControlSet -> Services -> Dnscache -> Set Start to 3. In our case it was set to 4. Lastly, and you should know this by now backup the registry before making edits. Thanks! -M

    Hi ,

    Thanks for your sharing. I will sort out the question and answer.

    Question:

    Recently upgraded some Windows 7 clients to Windows 10, unable to access SMB shares/re-join or join a domain.

    Solution:

    Looking in Event Viewer at: App and Services Logs -> Microsoft -> Windows -> SMBClient -> Connectivity. There were error events that the server name could not be resolved.

    Upon checking services the DNS Client was disabled.

    Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dnscache , locate the Start registry key and find the value is 4 (Disabled).

    Set Start registry key to 3. Then the problem will be solved.
