The test failed because Windows didn't assign IPs to all NICs immediately after boot. A loop was added to check the NIC count until all are initialized, ensuring the test waits for all NICs to get their IP addresses before proceeding.

We need to setup an end condition for the while block, otherwise it might get stuck in an endless loop.

The test failed because Windows didn't assign IPs to all NICs
immediately after boot. A loop was added to check the NIC count until
all are initialized, ensuring the test waits for all NICs to get their
