Autocad 2000 and XP PRO

[tcs]

I have upgraded several computers from windows 98 to XP Pro with SP2. I am running Autocad 2000 and have issues printing to the designjet 450c through windows 2003 sbs server. I can print flawless from the remaining windows 98 box but i have diffrent output from xp. Mainly the image will stop printing and or the data will show only hidden lines then the nex time it will print the solid lines ect... I have tried running the autocad 2000 in windows 2000 compatability mode but i still get some errors. Help

P.S.
Does anyone know where i can get patches for autocad 2000?

Thanks in advance!
