[jcifs] Every 2nd Connection fails

[nicholas new]

Hallo everybody!

I am new to jcifs but have managed to get it to work. I am using it to connect 
to a Windows 2003 Server from a PL-SQL programme running in an Oracle database,
in order to download and view a PDF file.
Every 2nd time I run the Programm I get the error message below. 
I have tried connecting to another Windows machine and have also run the 
programme itself on a different machine (both Solaris).
The behaviour was the same.
If I make and close the connection twice in the Java part of the programme 
there is no error. So I am very perplexed.
Any ideas would be most welcome! 
jcifs version: jcifs-1.2.7.jar
java version on the DB: 1.3.1

Thanks a lot!

Best Wishes

Nicholas New
