Do SQL Native Client connections need to be reopened after a complete failure of the principal server in a mirrored env?

Question

I have a connection string as below:

DRIVER=SQL NATIVE CLIENT;SERVER=TCP:NYAVDEVINTDCDB1,5550;
FAILOVER_PARTNER=TCP:NYAVDEVINTDCDB2,5550;DATABASE=DMINTDC;
TRUSTED_CONNECTION=YES;POOLING=TRUE;

Do SQL Native Clients using this connection String have to perform a reconnect when the NYAVDEVINTDCDB1 server gets completely disconnected or loses connectivity from the network? If not, why do I get a

[SQL Native Client]Communication link failure

when this situation arises?

I am using SQL Server Standard Edition 9.00.3152.00 SP2

Answer 1

Clients need to reconnect in the event of a failover.
