Has anyone experienced anything this problem before? I have tried alot of the approaches suggested on this mailing list (eg setting local network addresses, changing jcifs.resolveOrder and domainController properties) but none have worked.<br><br>I would appreciate any advice or troubleshooting tips that you may have.<br><br>Thanks,<br><br>Venn<br><br><hr id="stopSpelling">From: venn.hardy@hotmail.com<br>To: jcifs@lists.samba.org<br>Date: Mon, 27 Jul 2009 13:42:47 +1030<br>Subject: Re: [jcifs] Changing domain controller causes "UnknownHostException: Faoled to negotiate with suitable domain controller"<br><br>

I forgot to mention before that I am using jcifs-1.1.11. But the same problem happens when I upgrade to jcifs-1.3.11<br>
<br>
Does anyone have any ideas on what might be causing this UnknownHostException: Failed to negotiate with suitable domain controller error?<br> <br>

Hello I have been using jcifs-1.1.11 in conjunction with a windows 2003 domain controller for some time now. Recently I have been doing some testing against a Windows 2008 domain controller and I have been having some problems with a line in my application: SmbSession.getChallengeForDomain();<br><br>That line causes this error:<br>java.net.UnknownHostException: Failed to negotiate with a suitable domain controller for TESTDOMAIN<br> at jcifs.smb.SmbSession.getChallengeForDomain(SmbSession.java:132)<br> at mypackage.cas.web.flow.ntlm.ProcessType1NtlmMessageAction.doExecute(ProcessType1NtlmMessageAction.java:74)<br> at org.springframework.webflow.action.AbstractAction.execute(AbstractAction.java:204)<br> at org.springframework.webflow.AnnotatedAction.execute(AnnotatedAction.java:139)<br> at org.springframework.webflow.ActionExecutor.execute(ActionExecutor.java:58)<br> Truncated. see log file for complete stacktrace<br> <br>Does anyone have any ideas on what might have changed on the windows server 2008 domain controller to make this error occur? And the steps I can take to make it work again?<br> <br>Thanks<br> <br>My jcifs.properties file looks like this (it connects to the new domain controller where I have been doing my testing):<br>jcifs.smb.client.soTimeout=300000<br>jcifs.smb.client.domain=TESTDOMAIN<br>jcifs.netbios.cachePolicy=1200<br>jcifs.netbios.wins=newdomaincontroller1<br>jcifs.http.loadBalance=true<br>jcifs.util.loglevel=3<br>jcifs.resolveOrder=DNS,LMHOSTS,WINS,BCAST<br> <br>I did an ethereal packet sniff against the existing domain controller and this is what I get (it works):<br><br>With DOMAIN domain and pointing to existingdomaincontroller<br>Source Destination Protocol Info<br>MyPC existingdomaincontroller NBSS Session request, to *SMBSERVER<20> from JCIFS102_122_AA<00><br>existingdomaincontroller MyPC NBSS Positive session response<br>MyPC existingdomaincontroller SMB Negotiate Protocol Request<br>existingdomaincontroller MyPC SMB Negotiate Protocol Response<br>MyPC existingdomaincontroller SMB Session Setup AndX Request, User: DOMAIN\RSTVHH; Tree Connect AndX, Path: <a>\\172.20.96.252\IPC$</a><br>existingdomaincontroller MyPC SMB Session Setup AndX Response; Tree Connect AndX<br> <br>However when I point to the new test domain controller, I get "Negative session response, Called name not present".<br> <br>With TESTDOMAIN domain and pointing to newdomaincontroller <br>Source Destination Protocol Info<br>MyPC newdomaincontroller1 NBSS Session request, to *SMBSERVER<20> from JCIFS102_122_BC<00><br>newdomaincontroller1 MyPC NBSS Negative session response, Called name not present<br>MyPC newdomaincontroller1 NBSS Session request, to TESTDOMAIN<20> from JCIFS102_122_BC<00><br>newdomaincontroller1 MyPC NBSS Negative session response, Called name not present<br>MyPC newdomaincontroller2 NBSS Session request, to *SMBSERVER<20> from JCIFS102_122_BC<00><br>newdomaincontroller2 MyPC NBSS Negative session response, Called name not present<br>MyPC newdomaincontroller2 NBSS Session request, to TESTDOMAIN<20> from JCIFS102_122_BC<00><br>newdomaincontroller2 MyPC NBSS Negative session response, Called name not present<br><br><br>
