Thanks for your input, but this isnt the report i was after. I think the one I managed to bugger up was a custom report. It listed all new software listing the .exe file against the computer name.
May have to resort to restoring the database to find the flipping thing.
For example it used to find:
"rpcnet" every time it was used
and any other software that had been installed.
Hope there is an easier way than the database restore!!
Thanks again for all your help
