[jcifs] Error message connecting to DC under load

[Ingo Rockel]

Hi all,

one of our customer reports problems with jcifs connecting to its DC. 
Sometimes a user can't login while later he is able to do so. The 
following error is logged, if the login attempt fails:

<NETBIOSUSERNAME>: 0xC0000072: jcifs.smb.SmbAuthException: Logon 
failure: account currently disabled.
jcifs.smb.SmbAuthException: Logon failure: account currently disabled.
         at jcifs.smb.SmbTransport.send(SmbTransport.java:659)
         at jcifs.smb.SmbSession.sessionSetup(SmbSession.java:189)
         at jcifs.smb.SmbSession.send(SmbSession.java:148)
         at jcifs.smb.SmbTree.treeConnect(SmbTree.java:134)
         at jcifs.smb.SmbSession.sessionSetup(SmbSession.java:183)
         at jcifs.smb.SmbSession.send(SmbSession.java:148)
         at jcifs.smb.SmbTree.treeConnect(SmbTree.java:134)
         at jcifs.smb.SmbSession.logon(SmbSession.java:85)
         at jcifs.smb.SmbSession.logon(SmbSession.java:80)

where I replaced the user name with <NETBIOSUSERNAME>. I was unable to 
isolate the problem on a test system, so can't set jcifs into debug at 
the moment, as the problems only occurs in the production environment.

How  does jcifs reinitialize its list of available DC or just keep it up 
to date? They have a quite big forrest and about three DCs in every domain.

Any suggestions, ideas, possible misconfigurations?

Regards,

	Ingo
