GIT Problem/ISSUE

Dear Git Team,


I'm having some trouble with my git software. I just would like to 
'pull' a project out of a repository.

At the beginning git worked just fine but since a few days ago I'm 
constantly getting the error:

Couldn't resolve host 'gitlab.lrz.de'

git did not exit cleanly (exit code 128) (391 ms @ 14.11.2016 16:53:37)


To my architecture: I'm having a Windows 10 Pro Version with the Intel 
U6600 processor.

I have Kaspersky running (But, indeed, I also tried it to shut this 
software down while testing git - additionally I killed all tasks which 
could considered to be a firewall)

Furthermore, I tried to use the ssh protocoll which did'nt worked out, 
as well.

I added a ssh key changed the environment variable. Didn't worked as well.

I have a direct link to the internet (in particular I'm not accessing 
the internet via a proxy)


A reinstallation of the software did't helped neither.


For your help I would like to thank you already in advance.


Kind Regards

Robert Fellendorf
