TeamViewer doesnt connect over LAN (WinPE environment)

[JP]

Hello,

I need to build a WinPE 3/4 (tested both so far) with Teamviewer access.
The problem is, the only version which "works" is the v5, everything above 5 doesn´t even start up.

So I did set everything up. First I´ve tested the access via Teamviewer servers (ID), which worked.

Then I tried to connect over LAN (entered the IP) - then there comes an errormessage saying. "Protocol negotiation failed."
See the log.

Code: [Select]

I guess WinPE lacks of some service/feature which is needed by Teamviewer to successfully connect via LAN?!

Thanks for any suggestions.
