[Samba] RPC, DCOM, 1745 and Other Errors

[James]

Hello Thomas,

     I've only been able to get shares working correctly if I gave the 
file share read,write, execute for all permissions(chmod 777). I then 
use Windows to set the ACL's. Based on the Wiki it's not needed but I've 
never had any luck without using it.

I then click on the "System Tools" section to expand it and I get "Event Viewer cannot connect to the computer FS1: The error reported is the RPC Server is unavailable"  I click OK on the error and it then say again it is connecting to FS1 and expand the section where I can see the Shared Folders.  As soon as I expand shared folders and click on shared I get the following "You do not have permissions to see the list of shares for Windows clients" and I will not let me see the shares.

When I go to computer management and connect to the DC (AD1)it connects, but when I expand System Tools, I get the following error "The Procedure Number is out of Range(1745)"  However after clicking "OK" on this error I am able to see and manage the Share and permissions as expected
