Dear all,
i've problem when establising next replica on sql 2012 always on after 2 nodes already established.
i already repeat the step with different scenario :
1. established in with apply 3 nodes on the same time.
2. established in with apply 2 nodes, after established then continue with next node.
both of the step in the last step of adding replica wizard after validation will result
dialog with text : "An item with the same key has already been added. (mscorlib)"
other info :
the 3 nodes using windows 2012 clustering with role sql always on and join into the same domain network.
All using windows 2012 Std Edt x64 , and 3 nodes using sql 2012 enterprise x64
Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64)

Enterprise Edition: Core-based Licensing (64-bit) on Windows NT 6.2 <X64> (Build 9200: )
but before this happened we have problem on dns server, so we reinstall the dns & ad, and recreate clustering and rejoin again the 3 nodes.
And previously before recreate dns server, all of the 3 nodes worked normally with always on (2 sync, 1 async)
i also check sys table to check if theres duplicate but no luck in msdb libary ff878305(sql.110) (sorry link cannot be write here due restricted)
please help.... how can i resolve this 'duplicate'?
