The dialog window asked to input username and password, but it always said incorrect password. But if I switched IPv6 to IPv4, I can sucessfully access using the same username and password.By the way, I was using the same machine as the client to access the server.

I am facing the same problem with Vista machine

According to http://technet2.microsoft.com/windowsserver/en/library/1e7541f2-1134-45b5-871a-bbb3ac7a94151033.mspx?mfr=true, Windows 2003 IPv6 supports File Sharing. But I can not access the sharing folder of another machine through IPv6 address or host name either. I don't know why? It's said on the microsoft web site that win2k3 do not support IPv6 literal address. So I also tried the original IPv6 too. However it still can't work either.

1. Enable DisableLoopbackCheck to allow such access even from localhosta. Click Start, click Run, type regedit , and then click OK. b. In Registry Editor, locate and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa c. Right-click Lsa, point to New, and then click DWORD Value. d. Type DisableLoopbackCheck , and then press ENTER. e. Right-click DisableLoopbackCheck, and then click Modify. f. In the Value data box, type 1 , and then click OK. 2. Reboot the server.

While this works, it seems that IPv6 support for UNC names is not functioning as intended against the local machine when using IPv6 literal addresses (possible bug?) The KB which discusses this specifically states: "Additionally, you can access the server on the local computer by using the following paths: \\IPaddress-of-local-computer \\Netbiosnameor \\ComputerName" While this works for the following address types, for example in Windows Explorer on Windows-7 & Server 2008 R2: IPv4 loop-back address (e.g., \\127.0.0.1\c$) IPv6 loop-back address (e.g., \\--1.ipv6-literal.net\c$) IPv4 network address (e.g., the machine's DHCP address) it is completely broken when "IPaddress-of-local-computer" is an IPv6 literal address; e.g., <localhost-full-ipv6-address>.ipv6-literal.net. This is a bit inconvenient for our current project, where I am trying to write Unit Tests on code to which we are adding IPv6 support. All developers will need to apply the DisableLoopbackCheck in order to run the unit tests, and we will need to apply the same change to all of our build machines. Is there an alternative which allows access to the local machine's file system via IPv6 literal addresses, but does not resort to modifying the registry & rebooting? -- James

Hi James, what error do you get when you do \\localipv6? What is the version of OS you have?Regards, Amit Saxena
