Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
Just to add to that I can't see that the document referenced by PKH actually mentions the registry keys for Catalog debugging:
HKEY_LOCALMACHINE\Software\Symantec\Backup Exec for Windows\Backup Exec\Debug\Enabled
HKEY_LOCALMACHINE\Software\Symantec\Backup Exec for Windows\Backup Exec\Debug\Verbose
Should both be set to 0 (which turns off the extra debugging)
Also if the catalog path cannot be changed in Beutility or inside the BE Admin Console, then as long as a CASO/MMS setup is not involved you can change it via the registry
a) Stop the services, Move (or copy and then delete when happy) the existing Catalog folder to where you want it to be.
b) Then change
HKEY_LOCALMACHINE\Software\Symantec\Backup Exec for Windows\Backup Exec\Engine\Misc\Catalog Path
c) Then start the services again.
