2 NIC card in PC

I have 4 pc
each have 2 network card.
1 NIC for Local Intranet and Internet use
2nd NIC for private use .. link to a switch box running private ip 192.x.x.x for printing to 1 specifc printer for the 4 pcs.
When i boot up pc, i am able to print.
Using Cmd, i am able to ping the 2 ips i am holding, for NIC1 and NIC 2,
but unable to ping beyond the segment i am in.
After i disable and re-enable back the 2nd NIC, i am able to ping beyond my segment.
Each time i reboot the problem will recurs, unable to ping beyond my segment again till i did the above steps.

Any solution?
