This error message is either from windows firewall or a routing issue. Check your default gateway and if it is not the UC make sure that you have routes to all VLANs (example 192.168.10.0, 10.1.1.0, and 10.1.10.1).

If you are using a firewall as your default gateway make sure you have routes to 10.1.10.1,10.1.10.2 and 10.1.1.0 from the firewall to the VLAN 1 interfaface.
