Volsnap Event ID 25 & 27

[Guest Mason]

Ok, so I have been having this problem with system restore erasing all of the

restore points on every boot up. With the help of some people on here, I

found the error that boldly states, "yep, I erased the restore points," and

they are as follows:

 

The first:

Volsnap event id 25:

 

The shadow copies of volume C: were deleted because the shadow copy storage

could not grow in time. Consider reducing the IO load on the system or

choose a shadow copy storage volume that is not being shadow copied.

 

And the second:

Volsnap event id 27:

 

The shadow copies of volume C: were aborted during detection because a

critical control file could not be opened.

 

How do I fix these errors? I have found KB articles for windows server

2003, but the registry modification that they suggedted doesn't work for me.
