Weird error when starting Tomcat 4

[Hugo Hendriks]

Hi,

I just installed Tomcat4 on win2000. It all seemed to work. When i called
localhost:8080 I got the Tomcat4 homepage. After I rebooted my system, i
wanted to start Tomcat but got the message, address in use, JVM_Bind.

I got this error before when i was building an application in jbuilder
whiched used tomcat as an testing environment. Couldn't use it then either
but after an reboot, it worked again.

Anyone knows this prob?

thx
