Unable to install Backup EXEC 2010 R2 on Server 2008

[yowoobaby]

Hi,

I'm trying to install Backup Exec 2010 R2 version on Windows Server Enterprise 2008 Sp2 64Bit.

1. Install OS.

2. Perform Windows update.

3. Domain Join.

4. Environment Check for Backup EXEC.

On the process of 'pre-installation', I got only one error as below screen shot.
Because of this error, I cannot install Backup Exec.

If I disjoined the server from the domain, I cannot see the error.

but if I did domain joining again, the error occurs.

I did domain joining like 4 times, but the error's never disappeared.

Is there something I have to do on DC policy?

I changed Server Name and rejoin it to the domain.

Then it's working fine.
