[jcifs] TransportException

[Claudia Bars]

Hi,

I've been testing NTLM HTTP Authentication on Windows platform. Container is 
Tomcat.
It's working fine, but sometimes, i get the unexpected following exception:

HTTP Status 500 - 

--------------------------------------------------------------------------------

type Exception report

message 

description The server encountered an internal error () that prevented it from 
fulfilling this request.

exception 

jcifs.smb.SmbException: 
jcifs.util.transport.TransportException: Transport1 timedout waiting for 
response to SmbComSessionSetupAndX
[command=SMB_COM_SESSION_SETUP_ANDX,received=false,errorCode=The operation 
completed 
successfully.,flags=0x0018,flags2=0xC003,signSeq=0,tid=0,pid=40039,uid=0,mid=54,

NT,NATIVE_LANMAN=jCIFS]
	at jcifs.util.transport.Transport.sendrecv(Transport.java:74)
....


That's my web.xml:

<filter>
	<filter-name>NTLM HTTP Authentication Filter</filter-name>
	<filter-class>jcifs.http.NtlmHttpFilter</filter-class>

	<init-param>
		<param-name>jcifs.http.domainController</param-name>
		<param-value>10.16.65.7</param-value>
	</init-param>

</filter>

<filter-mapping>
	<filter-name>NTLM HTTP Authentication Filter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>


I've been checking environment and network troubles, but i got no conclusive 
report about it.
Does it have something to do with network? Any idea?

Thanks in advance
