My windows networking started failing intermittently a couple of weeks ago, I was able to restore by re=booting my server but now recently can not be re-started after booting. I have replacing the ethernet hardware which did not help and checked syslog and found this, any suggestions on what I need to do to fix problems below, I did run Memtest with no errors, complete syslog is attached

What do you get with?

Thanks trurl for taking a look, here's what I get

Ok, looks like the problem might have to do with windows 8.1 and their most recent round of security updates, I am able to access my unraid SMB shares from my windows 7 PC's but not my windows 8 PC's, I will post more after I figure it out.

 

Als i'm going to take a guess that the portion of the syslog I posted above might mean I should update my BIOS, I have a supermicro C2SEA with BIOS version 8.00.15  dated 10/08/08

Found the problem, under "Advanced sharing settings" I had to switch from "Allow Windows to manage homegroup connections

(recommended)" to "Use user accounts and passwords to connect to other computers" not sure why it all of the sudden became a problem.

 

Still need to figure out the BIOS message above, maybe i'll start a new post with that as the subject.

Spoke to soon, I can access shares just have no write access even though I have me as the user set to read/write under shares in unraid

Clear any unRAID credentials on the Windows machine in Control Panel - Credential Manager. And/Or

net use * delete

from a Windows Command Prompt.

 

Is unRAID configured as the Local Master? (unRAID Settings tab, SMB Settings)

I had cleared credentials earlier and that did not help, the net use * /delete responded with an empty message. Yes my UnRaid PC is set to Master.

 

I did get one of the win 8 PCs to work again by switching to "Use user accounts and passwords to connect to other computers" and back to "Allow Windows to manage homegroup connections (recommended)" the other lets me see the shares but gives me no access when I try to open them.
