Clarification reg Domain Controller IP address change

[Former Member]

Hi,

We are running on Windows MSCS Cluster (Primary / Secondary) for ECC Server.

The MSCS Cluster environment of ECC Server is a member of a Domain Controller.

We are planning to replace the Domain Controller, nevertheless all the settings / user names will remain the same.

The only thing will be changed is the IP Address.

For changing the IP address, we are planning to change the DNS and WINS IP address of the ECC Server accordingly.

Hence needs clarification on the following 2 points:

1. Is OS / SAP System Restart Required ??

For changing the DNS and WINS IP address of ECC Server,

whether the OS / SAP system has to be restarted ?

2. Effect on SAP System / Setting Change required on SAP

We would like to know whether there will be any issues with regard to SAP System Operation.

Especially we would like to know whether any setting changes needs to be done in the SAP System also.

Best Regards

1) you need to restart database and SAP at a minimum. To be on the safe side, I would also reboot server.

2) I would check things such as RFC connections of all system connecting to your system. Also check any thrid party toosl sucha s monitoring, faxing, Vertex, iXos etc...

Hi Eric,

Thanks a lot for your reply.

Kindly confirm only one more thing.

Hope there should be no setting change required in the SAP System. Am I right ?

Thanks and Best Regards

Hi Raghu,

No need to make any changes from SAP side.

SAP work on hostname and FQDN, so changing the ip address will not be problem.

But , as eric said after make changes you have to check all the RFC which should work fine.

thanks
