In windows 2012 with two NIC cards the first Network Card IPAddress is used to bind by the CA SAM Integration Service of the Spectrum Connector server.
In some environments the first NIC is not reachable but the second NIC is the correct one which has to be used for communication.
ping -4 <hostname> returns the ipaddress of the first interface but this is not reachable.
route print will show that the Interface Metric of the first interface is higher than of the second one.
Do a route print and you will see something like this, for example:
220.127.116.11 255.255.255.255 On-link 18.104.22.168 306
10.10.10.10 255.255.255.255 On-link 22.214.171.124 272
So the Interface Metric on 126.96.36.199 is higher than the Metric on 10.10.10.10
Try again the ping -4 <hostname>, it should return the interface with the highest metric.
If not, and still return the first interface, try adding the ip address with the highest metric to hosts file (C:\Windows\System32\Drivers\etc\hosts).
For this, edit the file, and make sure exist an entry as, and if not, add it and save the file.
where <hostname> is the hostname of the connector machine, and 188.8.131.52 the ip address of the interface with highest metric. The one it should use the connector.
Note: All IPAddresses mentioned in the case are examples and not from any real environment
