Backup Exec 12 AOFO Initialization Failure

I have Backup Exec 12 running nightly backups. I receive the following message in the job log with every backup:

"V-79-57344-34110 - AOFO: Initialization failure on: "D:". Advanced Open File Option used: Symantec Volume Snapshot Provider (VSP).
AOFO: Unable to get minimum quiet time for physical volumes. Reduce the activity on these volumes, or wait and run the backup when there is less activity on the volumes."

The backups always "Complete with Exceptions."  I have the option selected to let Backup Exec chose the Open File Technology and also have Process Logical Volumes for backup one at a time selected. The number of seconds during which there can be no disk activity before the snapshot is created is 5 seconds. The number of seconds that the application tries to obtain the minimum quiet time, after which the job fails is 2000 seconds.

My concerns are:
Are all the files still getting backed up, specifically the open files even though there is an "Initialization Failure"?
Has anyone had better success by chosing a specific open file technology, rather than letting backup exec choose?
Should I even be concerned with the "Completed with Exceptions" alert?  I hate to accept that alert as a successful job.

As stated in the article above, I de-selected "Process Logical Volumes One at a Time" on the backups.  It flushed the exchange transaction logs and Backup Exec defaulted AOFO to VSS, and now the backups complete successfully.

Try decreasing the idle time by one second then retest.  If this works all is well, if not reduce by one second again and test etc....

I received the following popup when I changed it to 4 seconds.  Should I be concerned with this?

I wouldn't be too concerned.  Due to several services that run on my network I have 10 out of 23 servers running with a 3 second timeout and have yet to discover a problem when performing restores.

I am down to a 2 second timeout with still no success.  Should I still go down to 1 sec?

Hmmm thats not good, 3 seconds is as low as I've ever had to go.
I think the next thing is too look through the services which are running and maybe end them one at a time.  After ending one service at a time, try the backup again.  This will then highlight the service(s) which cause the prioblem.  Once you identify the service we can look towards writing a pre & post backup command file to end the service and restart it after the backup.

This server is a file server/dns server.  What services would you reccommend I start with?

Compaq_EngineerCommented:
What is the server used for?  Just to give me an idea of what services may be loaded?

Its Server 2003 R2 used as a file server, dns server, backup machine, and ftp server.

As a first starter try stopping the dns & ftp server services, then run a backup.  Also are the backups taking place whilst users are logged on?

pghzooitAuthor Commented:
No users are logged on.  I really don't feel comfortable stopping services to run the backups, especially dns.  Do you have any documentation or articles that this works?

I have read an article on this ;- http://seer.entsupport.symantec.com/docs/258341.htm and had a similar issue years ago on NT4 with Arcserve 6.5.  I tried to use the Open File Agent but never really had any sucess so ended up stopping the DHCP service in that case.  I had forgotten about defragmenting the drive, which can be worth trying but I've never been sucessful.
