BucketMover moving to cold on UNC

I get the following error:

ERROR BucketMover - aborting move because recursive copy from src='C:Program FilesSplunkvarlibsplunkf5testwarmdbdb_1380909713_1380904989_18' to dst='\10.20.120.120SplunkNode01F5testinflight-db_1380909713_1380904989_18' failed (reason='The operation completed successfully.')

I is indication successful but i check the folder and there is nothing there.

I logged in to the server (windows 2012 R2) as the service account that runs splunkd and checked to make sure access was ok and im able to create/read/write ok. Also it created the F5Test folder when i added the cold path to the index so its not an access issue.

I ran procmon to see if it showed anything and I can see it trying to access the path

1:42:54.2746637 PM splunkd.exe 1684 CreateFile \10.20.120.120splunkNode01F5testinflight-db_1380909713_1380904989_18 NAME NOT FOUND Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a

So that seems normal, based on the fact that the file isnt there and it should be the Copy (CreateFile is used for a lot of things)

Is there something else i can do to look at why this might not be working?

thanks
