Unable to connect to windows share using hostname but works with IP address #363

Hi, I have a windows share that looks like this: //insurance_share/datadfs

When I try to connect to this windows share using the hostname above, I get a "Failed to connect to server" error. When I inspected the properties of this windows share, under DFS, it has a number of referral paths. When I use the hostname of one of these DFS, then the connection works.

When I did a ping in command line, I could get their IP address and the connection works using IP address.

Am I required to set any property in order to connect to the windows share using the original name (//insurance_share/datadfs) instead of relying on the DFS referral path or IP address? My configuration looks like this:

    Properties jcifsProperties = new Properties();
    jcifsProperties.setProperty("jcifs.smb.client.minVersion", "SMB311"); //tried with 202 also 
    jcifsProperties.setProperty("jcifs.smb.client.maxVersion","SMB311");  // tried with 202 also
    Configuration config = new PropertyConfiguration(jcifsProperties);
    BaseContext baseCxt = new BaseContext(config);
    NtlmPasswordAuthenticator auth = new NtlmPasswordAuthenticator(null, smbShareUser, smbSharePass);
    CIFSContext authed = baseCxt.withCredentials(auth);

Any help would be much appreciated 🙏 P.S: The machine type is windows 2016 server And the version of jcifs-ng I use is 2.1.9

For jcifs's domain DFS lookups to work you need to provide the domain name in NtlmPasswordAuthenticator. That may be the issue.
