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

[harikrishnanmurthy]

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.
