Sometimes the server administrator uses TCP/IP to filter the restricted ports, so that we cannot log on to 3389.
To remove this restriction, you only need to export the registry for modification:
TCP/IP filtering has three entries in the registry:
HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Services \ Tcpip
HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet002 \ Services \ Tcpip
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip
Export to the specified directory and modify it:
Regedit-e D: \ chouwazi.com \ 1.reg HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip
Regedit-e D: \ chouwazi.com \ 2.reg HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet002 \ Services \ Tcpip
Regedit-e D: \ chouwazi.com \ 3.reg HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip
And then put the following three files:
"EnableSecurityFilters" = dword: 00000001 "to" EnableSecurityFilters "= dword: 00000000"
Then, import the preceding three files to the registry:
Regedit-s D: \ chouwazi.com \ 1.reg
Regedit-s D: \ chouwazi.com \ 2.reg
Regedit-s D: \ chouwazi.com \ 3.reg
Restart the server!
