You will in fact find a bunch of hits if you google for this error code. 
Because only you know the software which is installed on your client, may i 
suggest you start from here.

Otherwise, stop the 2 VSS related services
  MS Software Shadow Copy Provider
  Volume Shadow Copy
and restart the NW service before a retry.
