I rather not use Teamviewer within my LAN since it is noticeably slower. The only thing is that I would prefer to be able to log into another PC without that PC locking. Is that possible? All the PCs have Win 8 Pro
Unless something's changed, officially, no. It's a limitation of the desktop version of remote desktop, one active session at a time. There is a couple *cough* unofficial ways around that limitation in the previous desktop versions of the OS, no idea if it's been done for 8 yet. I'd suspect it can't be mentioned here.
