Re: Issues connecting with DFS server

 Hello,

I also noticed this exception regularly occuring in the logs:

Caused by: jcifs.smb.SmbException: Transport38 timedout waiting for response to SmbComSessionSetupAndX[command=SMB_COM_SESSION_SETUP_ANDX,received=false,errorCode=0,flags=0x0018,flags2=0xC803,signSeq=0,tid=0,pid=29747,uid=0,mid=12322,wordCount=12,byteCount=107,andxCommand=0xFF,andxOffset=0,snd_buf_size=16644,maxMpxCount=10,VC_NUMBER=1,sessionKey=0,lmHash.length=0,ntHash.length=0,capabilities=-2147479468,accountName=null,primaryDomain=null,NATIVE_OS=Windows Server 2008 R2,NATIVE_LANMAN=jCIFS]

	at jcifs.smb.SmbSession.logon(SmbSession.java:147)
	at jcifs.smb.SmbSession.logon(SmbSession.java:140)


The issue is occuring randomly and although most of the pollings are successful sometimes these exceptions are thrown and the polling fails.

Any help will be appreciated!

Best regards,
M.D
