Just to clarify, this is not an issue with permissions but rather with the windows UAC prompt. When the VMware Converter tries to P2V a machine the UAC prompt is interfering with the request and timing out because you arent able to “OK” it.
So what we need to do is disable the UAC prompt from appearing by amending the local security policy of the remote machine.
How to amend the security policy
- Log into the server you’re trying to convert to a virtual machine.
- Open Local Security Policy (open run dialog and type secpol.msc).
- Go to: Local Policies > Security Options.
- Change “User Access Control: Run all Administrators in Admin Approval Mode” from Enabled to Disabled.
