I recently renamed the server that BES 10 was installed. Now I cannot access the BES admin login. Can I reinstall the product without losing any user information. Thanks, Roger

did you try by IP instead of FQDN?

[fadmin]

Try this:
On a computer that hosts a BlackBerry Administration Service instance, open the BES10 Configuration Tool.
If a Windows message appears and requests permission to make changes to the computer, click Yes.
2. On the BlackBerry Administration Service Pool tab, in the Pool name field, type the new pool name.
3. Click OK.
4. In the Windows Services, restart the BlackBerry Administration Service services.
5. On a computer that hosts another BlackBerry Administration Service instance, open the BES10 Configuration Tool.
If the BES10 Configuration Tool is already open, close it and then open it again.
6. On the BlackBerry Administration Service Pool tab, click Synchronize.
Configuration Guide Setting up BlackBerry Device Service components 73
7. Click OK.
8. In the Windows Services, restart the BlackBerry Administration Service services.
9. Repeat steps 5 to 8 for each BlackBerry Administration Service instance in the pool.
After you finish: Import the SSL certificate again to use the new pool name that you specified. See Import a new SSL certificate into the web keystore .
