Greetings-

Thanks for the post. I'll do my best to answer all your questions.

- Does this problem occur consistently?
Rougly 47 out of 50 times. We've had the server in production for
approximately 4 weeks. It's had three successful shadow copies: the first
one since it was configured, once when we were disabling/enabling the
scheduled Shadow Copy AND the Shadow Copy Service, and weirdly enough, this
morning.

As part of the troubleshooting process, I removed the original scheduled
event (2x a day @ noon and 7 PM) and created a new one (1x a day @ 6 AM)
This has not helped.

We are also getting the 12289 errors at times other than the scheduled
Shadow Copy time. For instance, yesterday the error showed up at 05:07:07
AM and 11:30:10 PM even though the schedule is set for 1x a day at 6 AM.

 - Can you manually create a shadow copy for
\\?\Volume{3848f961-a0a7-11d8-bbd1-505054503030} using vssadmin.exe?
Yes, I just did using the command line "vssadmin create shadow /For=e:
/AutoRetry=5"

- Did this volume ever have any shadow copies? - vssadmin.exe list shadows
can tell
As stated before we should've had three including today, but it lists only
the one from this morning. There is a event in the System Log from 6/7/04
indicating the other copies were deleted:

Event Type: Error
Event Source: VolSnap
Event Category: None
Event ID: 16
Date: 6/7/2004
Time: 4:40:37 AM
User: N/A
Computer: <SERVER>
Description: The shadow copies of volume E: were aborted because volume E:,
which contains shadow copy storage for this shadow copy, was force
dismounted.
Data:
0000: 00 00 00 00 03 00 58 00 ......X.
0008: 00 00 00 00 10 00 06 c0 .......À

0020: 00 00 00 00 00 00 00 00 ........

- Are there any special applications running on this machine which cause the
volume to be dismounted intermittently - such as chkdsk /x
The only thing(s) running when the errors are recorded at times OTHER than
the scheduled time are backups (Tivoli and ntBackup) There are no
applications running at the scheduled time when it fails.

- At the time this error happens, does the output of mountvol.exe contain
this volume?
The above event log entry would indicate to me that the answer to this
question is "NO"; Looking at the Event Log, this error has occurred 5
times:

Type Date Time Source Category Event User Computer
Error 6/9/2004 4:43:21 AM VolSnap None 16 N/A <SERVER>
Error 6/7/2004 4:40:37 AM VolSnap None 16 N/A <SERVER>
Error 6/4/2004 8:09:24 AM VolSnap None 16 N/A <SERVER>
Error 5/22/2004 4:32:37 AM VolSnap None 16 N/A <SERVER>
Error 5/20/2004 4:32:14 AM VolSnap None 16 N/A <SERVER>

A conflict with Tivoli? The setup is the same on our other File Server.
Will the #833167 Hotfix fix it?
