Thanks for the recommendations. I've been looking for a package like "help and manual" for ages. I'd always held off buying a package until I absolutely needed one. Glad I wait now that I've been shown H&M. This looks like it is exactly what I want. Of course I may change my mind once I've used it... Thanks to all that replied.

Try: EnumDisplayDevices

Sorry my comments didn't help. Can you use windbg on your system to read the Drwtsn32 "core" Dump files? This might give you a clue. (you got to make DrWtsn32 your default debugger and let it generate core files but I am sure you already read how to do this in John Robbin's articles...) You might want to change the debug info generation to "C7" compatible which is sufficient to read the line numbers and a get a function name context. Then again if you reinstalled the OS, everything might be running OK now. Good luck.

I don't have an solid answer for you, but FYI: Error code 1603 means: The file [2][3] is being held in use{ by the following process: Name: [4], Id: [5], Window Title: '[6]'}.

The number of things you can try is, unfortunately, nearly endless. Here's a few things off the top of my head: Could it be hardware? Some clone machines that have interrupt conflicts or flaky hard drives sometimes work, but work slowly. The hardware doesn't fail, just takes 3 retries to do everything. Check and see how many protocols you have set up. You likely only need TCP/IP, but maybe IPX for playing games too. Make sure the "default" protocol is the same for all the boxes (TCP/IP my recommendation), and remove anything you don't need. Some network cards don't play nice together. 100BaseT cards are like $20 ea, I'd just buy new cards for everything, get all the same brand. I like DLink there cheap and you can always find the right drivers. HTH
