DCOM error 10009

I have upgraded a ProLiant ML370 G4 with ProLiant Support Pack 7.40B.
After restarting the server, I wasn't able to ping or connect to another Domain Controller on the internal network. In the System Event Log I saw many DCOM 10009 errors (unable to connect to computer...).
Installation of PSP 7.40B changed the driver of one of the two NICs in teaming from NC7781 to NC7771.
Changed the driver of the NIC to the correct one, rebooted the server and all was OK.
