Error: 2147754774 - VMWare Standalone Converter

Hi dudes,

I can't do the backup of virtual machine (VMWARE Vsphere Hypervisor 4.1) using "VMWARE Standalone Converter 4.3". I tried to move this to another VMWARE Vsphere Hypervisior 4.1.

When started the process, Standalone Converter failed in 1% and return the message:

FAILED: Unable to create a VSS snapshot of the source volume(s). Error code:
2147754774 (0x80042316).

I tried to repair the vmware standalone converter, reboot the VM, restart all the services manually, the destination VMWARE Vpshere has disk space necessary for the copy ....

i didn't found any answer in the internet.

I dont know what happend !!!! please help!

thanks!
