Yes, thank you all for your assistance - I tried the bridged yesterday, and it picked up the DHCP address from the host servers' network - and that solution seems to be the best one at this point.
For the other posts about adding more RAM and using ESX - I would do that, but this is for my office, testing out a solution, and you would think that as "tight" as they are, you'd get diamonds from coal and we'd be able to spend some money... In the short term, I am using crappy workstations with 4gb each. Working on getting ones with 8 or 16gb, but you know how hard it is to order stuff in an office... Maybe I can do ESX down the road. Again, thanks for all your suggestions.
