Hello mrjoltcola sorry for getting back to you so late. Yes your solution did help I checked the environment variables and sure enough there were many differences. At one time this server was used as a test server so they had installed Oracle 8,9 and so on. All these were inbedded in the path variables .........after cleaning everything up and pointing everything to 10.2.4 guess what DUA came up no problem.
I can't believe it I should have checked this out first.

Thanks for your help have a great day.........
