Briefly unable to access network computer by name, just IP Address

    質問

  • Since our company changed routers, every couple of days, we briefly and just a few minutes and at random times, lose access to a key shared computer.

    When we are not able to access by name, we ARE able to access by IP Address.

    Within a few minutes or less, everything is fine.

    This is occurring on up to 4 computers, but not at the same time.  When one is unable to access, other's still can.

    Any suggestions?

  • Hi Mark,

    According to the symptoms, it should be the DNS issue.

    Since the issue occurs randomly and shortly, it's hard to trace it. Here I suggest you reset the DNS cache on all of these computers:

     1. While on the desktop, press WIN+X.
     2. Select Command Prompt (Admin).
     3. Type ipconfig /release in the command prompt.
     4. Wait a few seconds for a reply that the IP address has been released.
     5. Type ipconfig /renew in the command prompt
     6. Wait a few seconds for a reply that the IP address has been re-established.
     7. Type ipconfig /flushdns in the command prompt.
     8. Close the command prompt and attempt to make a connection.

    In addition, since it occurs after changing router, please also consider the router problem. Update router driver and firmware. Furthermore, contact router support to see if any solution.

  • Hi Mark,

    Did you use IP address or host name o access it?

    Do the following operations on host and guest computers:

    Step 1: Please open Services console, make sure the following services' startup type is "Automatic" and status is "Running".

    • DNS Client
    • Function Discovery Resource Publication
    • SSDP Discovery
    • UPnP Device Host

    Step 2: Turn on the network discovery for all network profile using command:

    1. Open Prompt command(Admin).

    2. Type the following command:

    netsh advfirewall firewall set rule group="Network Discovery" new enable=Yes

    Step 3: Check if those PCs set disable NetBIOS over TCP/IP in the NetBIOS settings:

    1. Open Control Panel \ Network and Internet.

    3. Click Change adapter settings.

    3. Right-click your connection, and then click Properties.

    4. In the This connection uses the following items list, double-click Internet Protocol Version 4 (TCP/IPv4), click Advanced, and then click the WINS tab.

    5. In NetBIOS settings, there are there options.

    Besides that, type ipconfig /flushdns in the command prompt as Admin to flush the DNS.

    Finally, reboot the computer to check the result.

  • I was using the Host name, not the IP Address.  IP Address continues to function.

    I'll try this shortly & thank you.

  • No luck with this latest change.

    Had a longer 30 minute lock out.

    I am able to ping the IP address & ping the computer name, if that matters.

    Neither the router or PC reset made a difference.

    While the PC was locked out, I released & renewed the IP address  & cleared the DNS.  

    Eventually, the connection was remade.

    Would it matter that the source computer is considerably more power than the locked out one?

  • Hi,

    What's message or just freeze?

    You can boot computer into Clean Boot to eliminate the third-party software and service:

    How to perform a clean boot in Windows

    https://support.microsoft.com/en-sg/help/929135/how-to-perform-a-clean-boot-in-windows

    That's randomly to hard to find out the culprit. You can refresh DNS & IP as a workaround.  If you want to find out the root cause, I suggest you open a premier support ticket. The premier engineer has a higher level, they may have more resources to help you.

  • Not a freeze, the prompt says that the user can't access the shared computer.

    Thanks for the suggestion on the premier ticket.
