[OpenIndiana-discuss] DNS Alias issue for CIFS - network path not found on Win7

[Sebastian Gabler]

Hi,

we are suffering for quite some time now from the notorious 0x8007003 
error on Windows 7 desktops in our network when accessing shares on our 
OI based file server over SMB. I am using the Solaris CIFS server.
It's an on-and-off issue, and I always had the impression that it had 
something to do with DNS resolution, even if it happened that it 
occurred even when using the pure IP address. Clearing the connection 
usually helped, but it's tedious for my colleagues and they often ask me 
for help about it.

I have found one thread over in the Open Solaris list on what appears to 
be the problem that ends with this message:

http://mail.opensolaris.org/pipermail/cifs-discuss/2011-May/003457.html

To sum up, the problem seems to be with the Windows clients. The issue 
that occurs is that the client assumes parallel connections to the same 
host over different paths. The solution offered by Oracle is a 
workaround that was implemented in Oracle's own branch.
Is that workaround also available in any OI or any other community-based 
Solaris distro?

Are there other methods to avoid the issue that anybody knows of? 
Currently the file server is not joined to our AD. Would joining 
potentially solve the issue?

Thanks for sharing your knowledge.

BR

Sebastian
