Hey All,

Just wondering if anyone else has experienced this.

Once in a while we get a failed registration due to a webservice error, or even due to an "invalid device GUID".

Suddenly, we're getting this on a whole group of machines.

Usually doing a zisedit -c to clear the ZISD information and zeroing out the first 50 sectors of the drive fixes this.

In the case of these machines, it's not fixing it.

I'm getting invalid device GUID over and over.
