Error: VSS error 0x800423f2


BA952 Volume Shadow Copy Error 0x800423f2 - writer error: timeout


This error occurs when the VSS snapshot exceeds the allocated timeout period before completing.


To resolve this error you can manually extend the VSS timeout by editing the following registry key:

HKLM\Software\\Microsoft\\Windows NT\\CurrentVersion\\SPP\\CreateTimeout.

Change value to 12000000 (2*10*60*1000 = 20 mins).

The default for the timeout period is 10 mins so hopefully doubling this will give enough time to complete the snapshot.

If this isn't present, you will need to manually enter the registry key. It is a DWORD 32-bit key.

See below for an example:
