When I browse to my own computer's shares by going to \\MYCOMPUTERNAME\ ; I cannot access any of the shares on my LOCAL machine (nor can I access them remotely) and it generates about 40 of the following errors in my system event log:

The following fatal alert was generated: 10. The internal error state is 1203.

Details:

  <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">

  <Provider Name="Schannel" Guid="{1F678132-5938-4686-9FDC-C8FF68F15C85}" />

  <EventData>
  <Data Name="AlertDesc">10</Data> 
  <Data Name="ErrorState">1203</Data> 
  </EventData>
  </Event>

Additonal information:

  • The process that is generating the error is lsass.exe
  • OS: Windows7 Professional x64
  • Joined to Domain: Yes
  • I was able to access the shares locally in the past
  • I am having the same issue on 3 other computers that have similar configurations

Any help would be greatly appreciated, because I have no idea what's wrong. Thanks!

I figured out my issue. I had port 444 and 445 bound to SSL on a local development website in IIS which was apparently conflicting with something (I'm not sure what it was conflicting with) After removing those bindings (SSL to 444/445) in IIS I was able to access my local shares without any issues.

Indeed, 445 is used by the LAN manager (SMB/CIFS) over TCP/IP, i.e. anything about network shares, pipes, mailslots ... it is a needed port. You mustn't tinker with it. Linux machines with smbd will usually also use that port. –  0xC0000022L Apr 10 '12 at 3:06
