Server Has Been Denied error

[Srdan]

Hi!

Few days ago all of the sudden I started receiving "Server Has Been Denied" error on my laptop and yesterday on one of the servers. All fixes that I could find are the same and are ineffective for my laptop because there are no registry keys left over after uninstallation, and in wireless NIC advanced options there is no Network Address Property.
On server there are also no keys left but Network Address Property is there, and by default it is set to Not Present. I don't want to change NIC properties because server is in a different city and I don't want to risk losing network connectivity.

Can You please tell me hot to fix this?
Laptop is running Windows 7 Enterprise x64, and the server Server 2012 R2 with TeamViewer 10 Corporate licence.
