I had this issue previously with Windows 2008 R2, and the issue was resolved by KB2663685 and KB2831101.
I've done an inplace update of windows 2008R2 in my file server - DFSR server, and after the update, I get again this problem:
My biggest folder stopped replication after an unexpected shutdown, and backlog count doesn't decrease . It's now more than 1.119.000
I've 5 replicated folder in the same drive unit, for about 2 TB of data.But the small ones replicate without problems
Any suggestion?
