Symptoms

When trying to view the information about client sessions by clicking Shared Folders > Sessions in the Computer Management console, it may take a long time to populate the information, and the console may stop responding or appear to hang.

Cause

Computer Management will try to resolve the client IP address to user-friendly NetBIOS name. In and IPv6 and IPv4 hybrid environment, and clients use NetBIOS to access share folders, if the NetBIOS name cannot be resolved, it shows the IPv6 address immediately. However, if clients are using ipv4 to access share folder, the failure of resolving to the NetBIOS name causes the Computer Management console to hang.

Resolution

1. Disable NetBIOS over TCP/IP:

   1. Run ncpa.cpl.
   2. Right-click the NIC.
   3. Select properties.
   4. Click TCPIPV4.
   5. Click advanced.
   6. Click WINS.
   7. Choose Disable Netbios over TCPIP.

2. Configure reverse lookup zone in DNS server. It is useful to computers that are added in domain.
