Eric, In all the versions I'm being 5.3 to 5.6 have the same problem.
The version 8.82 is functioning normally in this environment - and the version 9 also worked in the old environment.
Not mentioned, but the old environment is W2k8 with the new environment and W2012.
The problem is not necessarily the SQL Server, but the native client or Windows itself. Because the version of the OS is 64bit - observe a small problem, but have not found the real problem.
hugs, Lucio
