Dear Experts!

I have to backup Windows2012 server. It worker fine with 8.0.3 client, but we have to upgrade it to 8.2.3.

Unfortunately when we want to start a backup alwas ending with errors, we cannot open and cannot backup  any  files from the server.

I run the save process on the server, with debug mode:

save -D2 -b FILES C:\TEMP\dedupstat.txt

Debug output:

lgwstat: Failed to open file/directory

Writetracker: nsrwriter_stop: error: Null hProcess detected

Writetracker: nsrwriter_stop: error: releasing hWriterMutex

save workflow released nsrwriter lock

WriteTracked:nsrwriter_stop: Return FALSE

94693: save: The backup of save set: C:\TEMP\dedupstat.txt failed

94693: save: The backup of save set: C:\TEMP\dedupstat.txt failed

Any hints?

I tried:

- reinstall the client

- changing the service owner of the nsrexecd

- modify the peer certificates

Please help me to solve this problem ...
