Scheduled Volume Shadow Copy fails to run

I'll provide some background.
I have a VPN network spanning 3 counties, 4 offices. Each office had a PDC running Server 2003. 3 out of the four offices I cannot get volume shadow copy to run on a schedule. One of the offices the volume shadow copy service runs correctly when scheduled. (No errors appear in the event log when the service does not run)
The odd thing is when I manually tell the servers to run a volume shadow copy the process completes correctly. I have tested the ability to restore files on all 4 servers and it works properly. Currently I manually create the daily vsc on the three non working servers, but its a pain and I would rather not do that.
All servers are fast enough featuring Xeon 1.8 gig plus, some featuring dual processors.
The server in which VSC works correctly is a Micron netframe 3600 with dual 1.8 xeon processors. 1 gb memory, two mirrored scsi drives and a scsi drive to hold vsc.

The non working servers are
1. Micron 1800 with 2.4 xeon processor, 1 gb memory, 2 scsi drives mirrored with SATA VSC drive
2. Same as above server
3. Dell Poweredge 800 2.8 pentium 4 1gb memory, 2 sata drives

Could the problem with the servers be caused by mixing sata with scsi drives?? (i doubt this)

I'll provide any or all details requested,
Thank you.
Josh

hi josh

might be a stupid question....do you have the Task Scheduler service running on the servers?  This is what controls the scheduled VSS snapshots

Thank you for the response.
Yes the task scheduler is running. (Backup works just fine on the servers.)
The service is is running. I already checked and made sure the non-working machines had the same services running as the working machine.

Ok, if you go into scheduled tasks, are you able to view the properties of the scheduled task??  Or do you receive a "initialisation" error??

Hello,

I do recieve an initialization error. which reads: General page initialization failed: The data is invalid.

I am not 100% positive, but I believe I promoted all of the servers to domain controller before configuring VSS.

Ok.....try deleting the schedule and recreating it:

Steps:
1) Open the properties for the volume, select the Shadow Copies tab
2) select a volume and click "Settings"
3) click "Schedule..." and delete all the schedules. Press OK all the
way down.
4) Now, in the initial Shadow Copies property page the volume should
show as "Disabled". Press "Enable" to re-enable the volume.
5) Make sure that the scheduled tasks are working now.


Or another option is:


1. Copy the non functioning scheduled task from task manager and
paste it elsewhere.
2. Rename the original task
3. copy the newly renamed task back into "Scheduled Tasks"
(Whopefully now you can edit the properties)
4. Change the credentials of the job to use a different
user account (domain admin).
5. Delete the original (non-functional) task

Thank you for your assistance, with your suggestions and some google search I found this post located at:

http://www.certfaq.com/bb/ftopic26329.html

which states:

Solved the problem thusly:

Jan, I don't know if you've solved your problem, but I was able to finally
get everything working thanks to a tip from a user on this board. Try

1. Delete the offending "SYSTEM" account tasks in Task Scheduler.
2. Stop the Task Scheduler
3. Delete all files in C:\Documents and Settings\All Users\Application
Data\Microsoft\Crypto\RSA\S-1-5-18
4. Restart the service (I'd restart the server as soon as possible, too).

Hope this helps others out there struggling with the problem
