I came across your thread on the LimeTech forum. Johnathan and Frank both gave good advice. The only thing is Frank was trying to isolate your problem without addressing your security issues. I think Johnathan hit the nail on the head. In the end it's up to you but I don't see how adding a user for your Win 7 machine would hurt to try? Once you use Windows Credential Manager to save the login, you can bet Tower will show up in your network without you having to type it in.
Ok, once your updates finish, try creating a user in UnRAID and use those login credentials from Win 7. Go ahead and click the remember credentials checkbox. Let me know.
Ron,FWIW, I have WHS 1.1 w/PP3. On Win7 Pro and now Win10 Pro, sometimes File Exporer sees my WHS and sometimes it doesn't. I gave up trying to make it see my WHS 100% of the time. I just type in \\whs_server_name into File Explorer and it remains sticky for a while. On an earlier version of Win7 Pro, it did not seem to be an issue. I expect MS made a change in Win7 (for the worse) which they migrated to Win10. Just wanted to let you know you're not alone.
Do you also have yours set to public or is it setup with a user account (i.e. username and password)?
I just read on the LT forum that other users are reporting issues with accessing their shares on Win 10 with 6.2.4. What I found most interesting though was BRiT's post that he has no issues but has username and passwords setup:It's post #98 here:http://lime-technology.com/forum/index.php?topic=53511.msg521723#msg521723
