Pushing NetBackup Client on Windows server 2008

Hi all, 

 

Pushing the update of netbackup client  to Windows server 2008 clients, the remote installation fails with the following message "Unsuccessful Symantec NetBackup Client Install". I was able to update the NetBackup client on Win2003 servers without problem like this.

 

The update is from 7.0.1 to 7.5.0.5. I couldn't do even the first step to 7.5 version.

 

I attached the push install log for two Win2008 clients. 

 

It seems the Win2008 servers have a security policy enabled because when I try to establish a remote desktop connection I'm asked to enter my credentiales in a different logon screen to complete the action. The screenshots attached. 

 

I already asked the Windows admin for help on this, but I'll thank if my NBU team can give me some ideas to solve this issue :)
