    Hi

    I am having a problem creating a remote desktop connection to our servers over VPN. This has worked for many years. I posted the following on Microsoft’s server forum:

    When Windows updates are available for our work servers, I use my Windows 10 Pro home computer (from home) to establish a VPN connection and then use Remote Desktop to log on to the servers, install the updates and restart the servers. After they have restarted I log on again to make sure everything is OK. I use Remote Desktop Connection Manager V2.2 (RDCM) to do this – this allows me to establish a connection to all 4 servers at the same time. I have been doing this for several years using various methods with XP, Vista, Win7 and Win8.1

    I tried this a week last Thursday and although I could establish a VPN connection to my employers network, I was unable to establish a remote desktop connection. For example, I tried to connect to a server and the RDCM tries to connect but after between 5 and 10 seconds a message is displayed:

    Disconnected from server-name (Unable to establish a connection)

    I tried using Windows’ built-in Remote Desktop Connection (Desktop App), but it displays an error message saying

    Remote Desktop can’t connect to the remote computer for one of these reasons:…

    I have tried connecting using the server name (which is how I normally connect) and via IP address.

    Our work network has Remote Access installed on a member server. Staff can connect remotely only if they are members of a global security group named VPN and NPS has a policy defined that explicitly allows for this (the default NPS policies are disabled). The work network comprises 4 servers and 35 clients and uses a 192.168.0.xxx addressing range. It comprises a single Active Directory domain on a single 255.255.255.0 subnet. There are two domain controllers: 2012 R2 and 2008. Remote access connections to the network are routed via the gateway (a Draytek 2830) router using NAT.

    I have an LMHOSTS file on my home PC that identifies the domain and which maps the name/address of our data server. When connected via VPN I am no longer able to connect to the data server using either its name or IP address via Windows Explorer (nothing happens when I try this, I don’t even see an error message).

    I use Emsisoft Internet Security and have disabled the firewall (and all the components as well), but my PC is still unable to establish a Remote Desktop connection.

    I have tried resetting TCP using my admin account but saw the following:

    Microsoft Windows [Version 10.0.10586]
    (c) 2015 Microsoft Corporation. All rights reserved.

    C:UsersBlood>netsh int ip reset c:resetlog.txt
    Resetting Interface, OK!
    Resetting , failed.
    Access is denied.

    Resetting , OK!
    Restart the computer to complete this action.

    But it did not help.

    After restarting I enabled the Administrator account, logged on using the Administrator account and tried resetting TCP again but saw the same message and after restarting am still unable to establish a Remote Desktop connection. I have also tried restarting the work’s gateway router.

    VPN connections are handled fine and IMAP connections to our data server that hosts our mail server software (Mercury/32) also work fine.

    The only thing that has changed on my work network is that I have moved a wireless router from one part of the building to another.

    I cannot see any error messages in the event logs on my home computer nor on the remote access server at work or the other servers I was trying to connect to.
