Error -1001 and more


Recommended Posts

To get rid of persistent -515 and -519 errors I replaced all cables, all NICs and the switch. In the process I upgraded the server from Win 2000 to Win 2003.

 

Now the backup completes every time, but I get the following errors:

 

MapError: unknown Windows error -2.147.024.809

VssWEnumWriterMetadata: GatherWriterMetadata failed, winerr -2147024809, error -1001

 

and

 

File "C:\Documents and Settings\All Users\Application Data\Microsoft\Network\Downloader\qmgr0.dat": can't read, error -1020

 

-1001 means "Unknown Windows OS error", but since -2147024809 = 80070057H I see this error as a Win32 "Invalid argument" error. It might be unexpected and unhandled, but not unknown.

-1020 "sharing violation": Should this occur with Open file option?

 

What can I do to get rid of these errors?
