Vista Machine Takes Over Print - XP Printers Can't Print Afterwards

Hey all and thanks ahead

Background before the question
I work for an architecture firm and are the test subjects to upgradin
because we are the graphics department with all the programs that ho
memory and have all the 64-bit programs... Adobe Photoshop CS4, 3DS Ma
2009 and Revit 2008. I recently upgraded my machine to Vista Busines
x64 and all my co-workers except for one other (who also upgraded wit
me to Vista Business x64) are all on XP x86 machines

Okay, we have problems with the network printers that are shared on
server machine. Issue is, everyone can print all day til we print ou
something. (Yes, are machine recognize the printers... it is not a
can't see them or are they shared on the server). After it stop
everyone, we can keep on printing ourselves. The only way to fix it i
to reset the server machine to recognize the printer again

Is there any local fix from the take over from happening... or is it o
the server machine? Actually, what is the fix? Currently are work aroun
is to jump on a computer that hasn't been used by anyone for years (X
x86) to print

Thanks ahea
Tophe
