  • Hi All,

     One windows 7 PC cannot access the QNAP NAS shares? But rest of the other Win7 can access?

    Check followings

     1. Ping nas01 and ip both - OK

     2 try \\nas01 and \\ip - Failed with error 

    3. Check registry order and mem

    4 Try to map useing net use with domain user/pass- failed -error 64

    5. net view \nas01 or \\ip -error 53

    6. nslookup- fine

    7. Flush dns\registerdns \delete arp etc

    8. check adapter settings ( client for MS , remove IPv6)

    9.uninstal and reinstall

    10. remove from the domain and re add.


     Going crazy?

  • Hi,

    Thanks for your post.

    In order to troubleshoot this issue, you need to temporarily disable Anti-Virus and firewall on the client. Ensure that the port 139 and port 445 were opened on both server and client.

    Mapped Drive Connection to Network Share May Be Lost

  • Hi,

    Please try the following hotfix. Hope it helps.

    You cannot access a remote server that shares files and printers by using the SMB protocol from a computer that is running Windows Server 2008 R2 or Windows 7
