The problme is the existing wiring is a bit of a mess. They already have 2
routers splitting the T1 - one to their network and one to the existing
computers that are going to ultimately be on the SBS network. The routers run
to 2 different sets of switches in 2 different server closets. It's a bit of
a nightmare.. but the infrastructure can't be changed at this point (they're
non-profit and don't have the money to rewire the entire site. And actually
they have up to date Antivirus software (it's up for renewal this March).
