VSS can be a pain

If this is a systemstate backup error, it's not surprising.  Even with all
the MS patches on, and with VSSADMIN LIST WRITERS showing no error, you'll
occasionally have issues with VSS doing system state backups.
It will either clear up on its own, or you'll have to schedule a reboot to
make it go away.

OTOH, do you have TSM Open File Support enabled on teh Win2K3 client?  And
are you using it for something in particular?

I tell my customers NOT to enable Open File support on Windows except in
very rare cases.

Open File Support does not give you valid backups of most Windows locked
files (like SQL DB's, for example).  The only time you should use it, is if
you have a particular application that you know you can get valid backups
with Open File Support, and no other way.  And the reason to have it turned
off, is that if it is enabled you tend to get bogus errors like this from
it.

Dear all,

has anyone come across the following eventlog error message while backing
up a W2K3 client?

Volume Shadow Copy Service error: Unexpected error calling routine
MoveFileExW

TSM backups work, nothing in the TSM error log or schedlog. No change,
client has been working happily for quite a while like 1000+ others.
VSSADMIN LIST WRITERS returns no error.
I don't believe it is a TSM issue in the end.

I'm just curious as MS, IBM, google and the forum don´t come up with much
apart from NetBackup stuff from 2005 and Windows 2000 cluster errors dating
way back.

VSSADMIN LIST WRITERS returns no error.

TSM Server is Solaris9, TSM Version 5.5.2.1
TSM Client is Window2003, current os patches (deemed essential for VSS to
work, been through that)
TSM Client Version 5.3.4.0 (I know, out of service, but hard to keep up in
a large environment)

Thanks for your help, all the stuff on the forum is really appreciated!

Markus
