Not to leave things unfinished, here is the final word on this one: It must have been a software issue that was causing the reboots, after replacing every single part in the machine, it continued to have problems, I dropped a spare HD into the machine and did an express install, voila..worked. So after reinstalling 4.1-R back onto the machine's original harddrive, all services work again, just fine. One thing that I got a lot of is people commenting on problems they had with the 3c905 family of cards, in my case, however & using the 3c905b-TX, this was not the issue. (unless it's a problem in 4.1-Stable & not 4.1-Release... *sigh* John Straiton ClickCom, Inc. jks@clickcom.com (704)365-9970x101 > > Ok, as a follow up here's what else I have done: > > Replaced the case & powersupply > replaced both NIC's with a spare, individually with a Linksys I had spare. > > So with the exception of the HD and the data on it, EVERYTHING in > the machine has been swapped out.
