Backup of VM using vshadow fails if exchange server 2003 is installed in VM (Host OS win2k8 RC2)

hostos:- windows server 2008 rc-2

 

i  have installed exchange server 2003 on vm (win2k3 -sp2).

i tried backup using vshadow tool.

backup of vm fails in running state with error message

 

error: selected writer 'microsoft hyper-v vss writer' in failed state!
   - status: 8 (vss_ws_failed_at_prepare_snapshot)
   - writer failure code: 0x800423f3 (<unknown error code>)
   - writer id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
   - instance id: {f626102c-c846-4b9a-8f6a-b8f76db34636}

 

in paused state backup works properly. idea reason?

 

fyi:- screen display
