Shared Folder Fails to Be Accessed Because of the IPv6 Channel Adapter

Publication Date:  2015-03-10 Views:  996 Downloads:  0
Issue Description
1. Enter \\shared server IP address\shared resource name in the address bar of Libraries of the VM running Windows 7.
A "Windows cannot access \\shared server IP address" message is displayed, and the error code is 0x80004005.



2. Ping the shared server IP address on the VM running Windows 7.
The IP address can be pinged.


Handling Process
1. Log in to the VM running Windows 7 and run the following commands to disable the channel adapter created by using an IPv6 address on the client:
netsh inter teredo set state disable
netsh inter isatap set state disable
netsh inter 6to4 set state disable

2. Restart the VM.
Root Cause
1. The shared server IP address can be pinged on the VM running Windows 7.
− Check results of the shared server and clients are as follows:
− Port 445 of the shared server is enabled.
− The firewall of the shared server is disabled.
− The firewall of the client accessing shared services is disabled.
− Other clients in the same network segment can properly access the shared server.
The problem is probably caused by the VM.

2. No third-party plug-in is detected on the NIC of the VM.

3. A 6to4 NIC adapter is displayed in the NIC list in the Device Manager window of the VM. After the adapter is disabled on the VM and the VM is restarted, the shared server can be properly accessed.




Suggestions
In normal cases, IPv4 instead of IPv6 addresses are used. Therefore, the IPv6 channel adapter can be disabled.
