We have a windows 2008 R2 server and mostly windows 7 professional desktops.These desktops are a mix of wired and wireless, and most also use a VPN connection out of the office through a sonicwall to access the file shares. These systems for the most part are problem free.
We have 2 Lenovo Yoga ultrabooks with Windows 8.1. They are always wirelessly connected. They both use VPN as well to connect to the same drives as the windows 7 machines when on job sites. Yoga 1 - when in the office, the user is prompted for credentials when she tries to access the shares the first time. She puts in u/p and can then see them. Although it looks like Yoga 1 is on the domain - it is in the active directory, it is joined - I tried to rejoin it and I received an error of unknown computer. I didn't go domain to workgroup back to domain - I just went far enough in the prompts to see if it would recognize the computer and no go. So that's problem one and am interested if there are 8.1 issues with 2008 r2. the other yoga has some if not all the same issues but I never really hear about them.
problem 2 - And now neither Yoga can access the shared drives through the VPN. They get "An error occurred while reconnecting <drive letter> to <Share path>. Microsoft Windows network the network path was not found. The connection has not been restored. "The VPN appears to connect. A network engineer wrote a small script to access the drives for all the users since they couldn't connect to the drives when they brought up the VPN. I don't know if that is causing an issue now or not. I haven't hear any of the win7 having any issues with the VPN or shares.
Script (< > substitutes for data):
ping rm-s001 -n 15
net use z: \\<rserver>\principals /user:<username> <Password>
net use z: /delete
I'd like to get the first problem first. then move to second.
