Symantec Backup Exec remote agent installation error

When you try to install Symantec Backup Exec Agent to a remote computer you receive the following error:
"Error connecting to the remote server.  Ensure that the server is available, has WMI enabled, and is not blocked by a firewall.24"
To fix this problem try the following on the remote computer:
Run Group Policy Editor or the local group policy editor (gpedit.msc) and from the Local Computer Policy/Computer Configuration/Windows Settings/Security Settings/Local Policies/User Rights Assignments allow Administrators, Local Service, and Network Service accounts to "Adjust Memory Quotas for Process Properties" and Local Service, and Network Service to "Replace a process level token". Remote user must also be a member of Local Administrators group and Remote Registry service must be running.
Reboot the remote server to apply changes.
Try to install Backup Exec agent again after rebooting the remote server.
