sujithmdCommented:
I believe your issue is just a false reporting you can delete the corresponding registry key for Z drive from the below location . Don't forget to take backup of registry before making any changes.

janis101Author Commented:
i need

1. Description of the Problem.

2. Root Cause

Please help!!!
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Its possible left over by P2V process.

Unless a manual subst had been invoked, by a user.
janis101Author Commented:
its not a P2V process..its a V2V..Can u please elaborate if you dont mind?

z:\: => C:\users\Administrator..what does it mean?

What is subst?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
1. Substitution in use, drive letter z: mapped to c: drive. Its a virtual drive mapping, it does not physically exist.

2. Possible left over by P2V process or a manual subst had been invoked.

3. Easy to resolve by using subst delete.
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
P2V or V2V its the same process.
