Slowness to load the list of selection of job

hello

 

I'm having trouble loading the selection list to create / edit a job. It takes considerable time. One detail, which I believe is the problem, is the message that appears when you run the command VSSADMIN LIST WRITERS: "waiting for responses. These may be delayed if a shadow copy is being prepared." Already ran a script to register some DLLs, but without success.

 

Anyone ever had a similar problem or equal to this and found a solution? I called open with Symantec, but it is urgent, since I'm on stage deployment.

 

I'm with Backup Exec 2012 and updated Windows 2008 R2 Std updated.
