    Hi ,

    i have a problem configuring NTLM authentication on the Wyse S10 devices.
    Let me explain the situation :

    We have a Windows 2008R2 Standard with remote desktop services installed.
    Our thin clients are all Wyse S10.
    Firmware Version 7.0.0_30 (upgrade from 6.5…)

    The strange thing is , NTLM authentication worked just untill last night , when the server was updated with some security updates and SP1.
    I think , some of these updates (SP1) broke the NTLM connection…

    Now what happens is , when the S10 starts connecting it all goes well untill you have to type the user credentials in the NTLM box (where the correct domain is already filled in)
    The thin client always says “invalid userid and password” when typing the credentials , but i am 100% sure that the userid and password are correctly inserted!
    I noticed this problem already on a thin client which wasn’t updated to 7.0 BUT now , it seems , the updates break the connection…This looks strange to me because what other updates will break the connection..

    I already checked the registry of the server to check the NTLM authentication and it is set to
    network security : Send NTLM response only

    I already tried to audit the NTLM traffic but i am unable to trigger events in
    Event Viewer (Local)Applications And Services LogsMicrosoftWindowsNTLMOperational

    This is my wnos.ini file :

    Why do you think you should change anything in your Thin Client environment, when everything was working before you modified your server site?

    No, it is your server environment.

    OK, once again. You said that everything was working before you installed latest MS hotfixes. Now it is no longer working.
    Mayb there is an issue in WTOS but it worked before the installation of the HF.
