Troubleshooting Exchange 2007 backup failures using Symantec NetBackup 7

Hello!

I've had successful backups for some time now against my Exchange 2007 clustered environment.  After upgrading to NBU 7, I am now getting error code 69 (invalid filelist specification).  I am also not able to enumerate ANY resources when selecting items to back up in the policy options.  Also, when I log in to the client and attempt to enumerate items available for backup, I do not see any Exchange resources, whereas before the upgrade I did see these resources.

Here is the contents of the bpbkar log in after a recent unsuccessful backup attempt:

I would appreciate any pointers... I've been troubleshooting this for two weeks and have tried everything I can find on Symantec's support site (hosts file cleanup, verifying permissions on the NetBackup service account, rebooting the clients, etc...) and haven't been able to make any progress whatsoever.  I'm coming up on two weeks of not having the Exchange store backed up.

Thank you!
