IT solutions that work: The terminal server has exceeded the maximum number of allowed connections

Wednesday 22 May 2013

What:

Windows Server 2003/2008

Problem:

Can't log on to the server via RDP, disconnected sessions used up allowed number of connections.

Solution:

Quick solution:

Start > Run

Type in the following command and hit enter

mstsc /v:<server_name> /admin

Longer solution:

You can also log off users via cmd
Log on to any other server on the network

Start command line console and type in

query session /server:<server_name>

You should see logged on users, now using ID you can end selected session

reset session <ID> /server:<server_name>

Example:

reset session 3 /server:192.168.1.10

It is /v
If you have any doubts just run mstsc /?, you will get list of all available switches.

Simply create a bat file with anyname.bat and run with Admin rights. :) Copy the script below ......

@echo off
setlocal
call :Quiet>nul 2>&1
set key=HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing
for /f "Tokens=*" %%a in ('REG QUERY %key%^|find /i "%key%\"') do (
@echo REG DELETE "%%a" /F
REG DELETE "%%a" /F
)
endlocal
goto :EOF
:Quiet
NET START TERMSERVICE

Thanks :) Enjoy
