Windows server 2012 R2 to solve the "unable to complete the domain join, the reason is attempting to join the domain SID and the SID of this computer is the same."
When the system uses cloning, add the following domain is a problem. "Unable to complete the domain join, the reason is attempting to join the domain SID and the SID of this computer is the same."
Problem Cause;
Windows uses the SID to represent all the security objects (security principals). Security object including the host, domain computer accounts, users and security groups. Name Name method is used to represent a SID, you can allow the user to rename children need to update the ACL (access control list). The SID is a numerical code comprising a schema version number, a 48-bit ID value of the authority, a full 32-bit sub-position or RID values. SID value identifies the issuing authority of the proxy, the proxy is usually windows system or local domain. Sub-authority value identifies the issuing authority delegated, RID Windows is used to create a common unique SID SID used.
SID in the same process may be used alone without any problems. But within Windows, each account has a unique Security ID, you can at HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ ProfileList see.
SID is the only symbol used to identify the account, instead of the usual thought the machine name \ user name.
The existing clone virtual machine is installed the entire system partition cloned directly down, so there are multiple machines with the same SID, so that when you join a domain, will complain, is not working properly.
Modify way: Open complete clone of the virtual machine: windows / System32 / Sysprep / Sysprep.exe Check generalise option.
