Multihomed Citrix server

Our Network structure seems to be filtering LANMAN traffic, yet I have 8 old cdrom towers that are LANMAN. To get around this I thought I could use a small hub to connect the cdrom towers directly to a citrix server. All the cd will be accessed thatway anyway so I dont even see a need for RIP. To put it short it dont work!! The server can either see the cdroms via one NIC or can be seen by the network via the first NIC, but not both. Visability depends on binding order. ANY suggestions appreciated.
