I have a home network with a windows 7 computer, windows xp and windows 2000. The windows 7 and 2000 previously played nicely and I have a big old CAD plotter connected to a parallel port on the windows 2000 computer and was able to use it from the windows 7 computer. I was also able to access any file on the windows 2000 from windows 7. I havenít had the win 2000 computer on for a few months but recently needed to use the plotter. I now get a log on error when trying to access the win 2000 from the win 7, but it shows up on networks. The log on error window shows a domain with the name of the windows 7 computer listed as the domain name, but nothing is set to be on a domain. I can access the files on the windows 7 computer from the win 2000 computer with no issues in that direction. Windows 7 is always updating itself and I suspect thatís part of the problem. The xp machine never played well with the network but I was able to access files on the 7 machine from that, but the xp computer needs work for other reasons so itís not an issue at the moment. Any help would be appreciated, thanks.
