[jcifs] How would I trouble shoot a java.net.UnknownHostException?

[Todd Patrick]

I am trying to set-up JCIFS NTLM HTTP Authentication according to the
instructions on http://jcifs.samba.org/src/docs/ntlmhttpauth.html.

The exception that I am returning is:

java.net.UnknownHostException: DTN.COM
	
jcifs.netbios.NameServiceClient.getAllByName(NameServiceClient.java:292)
	jcifs.netbios.NbtAddress.getAllByName(NbtAddress.java:454)
	jcifs.smb.SmbSession.getChallengeForDomain(SmbSession.java:95)
	jcifs.http.NtlmHttpFilter.negotiate(NtlmHttpFilter.java:150)
	jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:114)

I ran a ipconfig /all and the information I returned is (I've masked out
the values, but you should get the idea):

C:\>ipconfig /all

Windows IP Configuration

        Host Name . . . . . . . . . . . . : xxxxxxxxxx
        Primary Dns Suffix  . . . . . . . : dtn.com

        Primary WINS Server . . . . . . . : 10.0.0.0
        Secondary WINS Server . . . . . . : 10.0.0.0

I would had thought that the Primary Dns Suffix would be the value used
for jcifs.smb.client.domain in the following set-up:

<filter>
<filter-name>NtlmHttpFilter</filter-name>
<filter-class>jcifs.http.NtlmHttpFilter</filter-class>
<init-param>
    <param-name>jcifs.netbios.wins</param-name>
    <param-value>10.0.0.0,10.0.0.1</param-value>
</init-param>
<init-param>
    <param-name>jcifs.smb.client.domain</param-name>
    <param-value>dtn.com</param-value>
</init-param>
<init-param>
    <param-name>jcifs.smb.client.username</param-name>
    <param-value>xxxxxx</param-value>
</init-param>
<init-param>
    <param-name>jcifs.smb.client.password</param-name>
    <param-value>xxxxxx</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>NtlmHttpFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

I'd appreciate any suggestions or thoughts on how to solve this issue.

Thank you,
