communication via the wrong network interface
I hope you can help me with an issue of our 4.6C system running on Windows 2003 R2.
When a user is establishing a connection via SAP GUI, this connection is made to serverprd on port 3600 in the server LAN - works fine.
However as soon as the communication goes to Port 3200, the communication goes via the backup LAN, which is configured as a 2nd network interface.
I tried to find out why the communication switches to the backup interface - I changed the order of the interfaces in the Windows network configuration, but no change.
The server has 2 IPs:
DNS Name IP Interface
serverprd 18.104.22.168 server LAN
serverprd-backup 22.214.171.124 backup LAN
There a re no host entries in the c:\windows\system32\drivers\etc\hosts
Does anyone has an idea what could else be tried?
Thank you for any ideas...
in the Windows (2008 R2) "Network and Sharing Center" click on "change adapter settings" (on the left).
There you can go to advanced -> Advanced settings...
In this window you can define the order of your network adapters.
