RDP - do not allow new connections broke my server

Question

Hi guys,

I am lost :(

I enabled 'do not allow new connections' in our RDP server as I did some updates.

Rebooted the server.

Went back in via Hyper-V, turned it off to allow new connections, and now I can't RDP from any machine to the server? Its as if its still set to 'do not allow new connections'

I am totally lost. What can I do and try?

:(

I've got to the bottom of it. I can't believe this but, it was my antivirus. The dam thing updated and decided to change the soft firewall. I decided to uninstall it just for testing, and I got straight in.

I just want to say, thank you for your attempted help.

Hi @Siraj Patel ,

you could try to get this fixed via PowerShell (just replace the SessionHost and ConnectionBroker values):

Import-Module RemoteDesktop  
Set-RDSessionHost -SessionHost "rdsh.contoso.com" -NewConnectionAllowed Yes -ConnectionBroker "rdcb.contoso.com"

Apologies but a question.

The users access the RDP from a local LAN via an IP.

Would this be correct:

Set-RDSessionHost -SessionHost "192.168.1.4" -NewConnectionAllowed Yes -ConnectionBroker "192.168.1.4"

Answer 4

Hi @Siraj Patel ,

based on the details of the link the SessionHost should be the FQDN (Full Qualified Domain Name) of the SessionHost. Same for the ConnectionBrowser.

The command should be run as an administrator of the RDS environment to modify the setting. But you could give it a try with the IP instead of the FQDN. It won't hurt but maybe it ends with an error.

IP didn't work but did it via FQND. Tested but its the same :(

Maybe its not the new connections allowed. I'm truly lost :(
