Keep losing network connectivity after reboot - Windows 2012 R2

We have a HS23 blades (Windows 2012 R2 Standard) using 2 x QLogic 10 Gigabit (Gb) Converged Network Adapters (CNA) QMI8142 for network connectivity.
We are using SanSurfer CLI to team the 2 physical network connections (Public network).
However, when the server is rebooted we can no longer remotely connect (over RDP) or get a ping response.  When connecting via blade center the IP settings (Default Gateway) for the team NIC is blanked out.  On disabling & renabling the team NIC we can then RDP to the server as normal.
I have been investigating for a few hours now & found some potential solutions, which do not work for me, namely:

I have also checked the biding order of the NIC's making sure that the physical NIC are in front of the team (virtual) NIC, but this hasn't made any difference.

Has anyone seen this before & fixed it.  Any helpful suggestions would be much appreciated.

thanks

We are using SanSurfer CLI to team the 2 physical network connections Why not use the built-in teaming in S2K12R2 ?

Funny you should say that - we actually reverted to using the inbuilt teaming from 2012R2 in the interim, which does offer a working alternative.  However from a consistantcy point of view - we ustilise sansurfer for all our blade builds & it's part of our build standard.
Thanks for the alternative option which does work, but do anyone have any direct solutions so that we can keep with our current standards?

I the end this appeared to be a driver & app issue. Now using the correct version & simply using the qlogic team management tab in the device manager for the network device. Works now using the preferred qlogic product.
