The two macs that I will have ( the G5 one running OSX 10.3, the other macpro, the intel one, presumably running mac OSX as well ) they will be linked into a windows 2003 server ( our whole office is PC based apart from these two macs.

Will the macs work fine running togther as render farm over the windows 2003 network  -  or can they/should they be linked directly one to another?

Any help really is appreciated  - I do the graphics, draw the pictures, but could do with knowing alot more . . . . 
thanks for help so far
