Hi
I am having the same issue (see below, I have removed the UUID in this instance, replaced with xxxx)
Last login: Sun Jan 25 12:20:36 on console
Signfits-iMac:~ admin$ prlctl list --all
UUID STATUS IP_ADDR NAME
{xxxx} running - Windows 7
Signfits-iMac:~ admin$ prlctl exec xxxx net user
User accounts for \\
-------------------------------------------------------------------------------
admin Administrator Guest
The command completed with one or more errors.
Signfits-iMac:~ admin$
and this has been happening for the past month. I did not set an original password, but got this message about 2 months ago, and although problem-solver 114193 worked then, it won't now. I cannot get support through the normal channels, as the website won't accept my support code (although I only purchased Parallels 8 in 2013, and I allegedly there should be two years support?!)
Parallels (or anyone!), please help resolve this! I have been struggling with this now for ages!
Thanks
Padmini
