NetBeans error resart app server

[Kris Reid]

I'm using NetBeans 5.0 and Sun App Server 8.2

In NetBeans when I click "run project" it tries to redeploy the application and always fails.

Deploying application in domain failed; Could not rename C:\Sun\AppServer\domains\domain1\applications\j2ee-apps\ProjectName to C:\Sun\AppServer\domains\domain1\applications\j2ee-apps\ProjectName_old

I have to then manually stop the app server then "run project" again.
It just takes ages and is really annoying, any ideas how to fix it?

Thanks a heap!
