"whitespace" problem encounter with client: VM Machine

Hi all:

One of our client (VM Machine) is failing with Status code: 4239 "Unable to find the virtual machine...".  What I noticed was that this client contained "whitespaces", i.e.,  USER.USER%20.  The only way to correct this was by deleting the client from the backup policy and adding it back "manually".

My question & concern is the following....  exactly how does NetBackup retrieves the VM name information from the vCenter and what attributes does it reads?  Is there any way to manually check for this information outside of Netbackup?

Thanks in advance!

Alex.
