---------------- mail from symantec --------------------
Hello
How are you today? Since I could not reach you on the phone, I am now following up with this email.
I have some good news for you today, I believe. As mentioned before, we could reproduce this issue in house and we have now managed to resolve it here by running a SQL command against our CMDB.
Therefore I would like to recommend the following steps for you:
1) Use SQL to back up your CMDB. This is best practice anytime you use SQL commands to access any database directly.
2) In the SQL Management Studio, run the following SQL script:
update Item
set name='new server name'
where Description like 'The owner notification server source item for'
Please note you will have to enter your own values in lines 2 and 3 of this script to have it match your own environment.
The machines should now show up with the new server name in resource manager.
