Hi Expert,

Sorry for my bad English but I hope you can understand. I have Samba version 3.5.2 and OpenLDAP: slapd 2.3.43 which running for about 1 year as PDC, and it running smoothly until last week. When I want to join to the domain with Windows XP, after I key in Domain Administrator username and password to join to the domain, an error message has appeared as below:

"Computer Name Changes
The following error occurred attempting to join the domain 'ABC'
The remote call procedure call failed."

Then when I click OK, my machine doesn't join to my domain. But when I check at the LDAP tree using Jxplorer, I can see my Windows XP computer name has been registered under Computers account, but I notice at SambaAcctFlags, the value was set to [DW], not [W] as other computers account. I don't know how it was set to [DW], as I know D means Account was Disabled. I have try to change the value to [W] and rejoin back the computer but the same error will come out and the SambaAcctFlags will change back to [DW].

I hope somebody can help me or maybe has experienced the same problem before and have the solution to fix it. Below is my smb.conf for your reference. Thank you again.
