can not ping after running Jboss

[raheleh]

Hi

I'm using jboss 4.2.2 and my OS is windows 2000. I'm using 2 systems and before running jboss I can ping each of the machines from the other one. But after running jboss on one of the systems I can't ping that machine? what is the problem :( ?
Thanks in advance for any help
Best Regards

You mean, there's no reply for the ping command? How do you start JBoss and what command do you use?

I use run.bat file of Jboss 4.2.2 which runs the following command

"%JAVA%" %JAVA_OPTS% "-Djava.endorsed.dirs=%JBOSS_ENDORSED_DIRS%" -classpath "%JBOSS_CLASSPATH%" org.jboss.Main -c all -b IPAddress%*

and when I ping IP -n 100, about 90% of packets lost.
I aslo wrote a simple client server program which the client send UDP messages to server (the machine that jboss is running on it). the server can't get about 90% of packets.
I tested it in another machines and the result was the same. :(
I really don't know what's happening and I'm very confused.

Thanks for your attention
