Code:
Terminal server No Restriction Patch 1.3 - Prefix #1
========================================
Just a compiled the script as normal - so it doesn't crash on non WinXP SP2 2180 Systems
- Antivirus poggie may detect "TS_Free.exe" as suspicious...
Purpose:
Remove all limitation of the Windows Remotedesktop/Terminalserver service
because of some 'restrictive' windows version like XP Home/XP Professional,
Small Business... or limits expose by licensing logic.
Usage:
Backup C:\windows\system32, termsrv.dll, winlogon.exe, mstscax.dll.
Start TS-Free-1.1.exe.
Check patcher output for error. Reboot.
Changes:
Files:
termsrv.dll
winlogon.exe
mstscax.dll
Registry:
[HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server]
"fDenyTSConnections"=0
"TSAdvertise"=1
"IdleWinStationPoolCount"=1
"TSAppCompat"=0
"TSEnabled"=1
"TSUserEnabled"=0
Licensing Core\
"EnableConcurrentSessions"=0
WinStations\RDP-Tcp\
"fEnableWinStation"=1
"MaxInstanceCount"=dword:ffffffff
[HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"AllowMultipleTSSessions"=1
Debugging:
If patch is not working compare if the modified version of the 3 files is
still in by comparing them with examdiff, Totalcommander or by windows onboard
Filecompare ("FC.exe /?")
The patch is only for 32-bit Windows. There currently no version for X64. Also
It doesn't work on windows vista (critical bytepattern changed so patcher
fails).
I someone really needs a 64-bit version and can give me a remote desktop connection
to the system contact me ;)
How it works:
TS-Free-1.1.exe is an rar-sfx archive which will extract all files
C:\windows\system32 and run TS_free.bat
TS_free.bat launches WPA-kill.exe that will remove the self checks from
winlogon.exe to make it patchable (and as also disable the product
activation check).
Ts_free.exe is the main patch that will modify
termsrv.dll
winlogon.exe
mstscax.dll
by a pattern search.
Note: patching of mstscax.dll is no really important. It just allows you
on XP Pro to connection with mstsc.exe to yourself (127.0.0.1)
Limitations/Known Bug:
On WinXP I discovered to following bug in previous version(1.1) of this patch:
After termsrv.dll was patched following steps brings up a 'can't connect':
Login locally as user1 , switch user - WinKey+L (or taskmgr/user/rightclick)
Login locally as user2 , switch user - WinKey+L (or taskmgr/user/rightclick)
Login/reconnect locally as user2 => Error!
Without patched termsrv.dll it works.
To solve this (at least on WinXP) a added to choice to apply/skip these so called
'additional patches'. On WinXP they somehow cause the problem.
They are related to the the 'Windows Version Info' constants VER_SUITE_TERMINAL and
VER_SUITE_SINGLEUSERTS. On server system I think 'additional patches' really
necessary because VER_SUITE_SINGLEUSERTS is not set. VER_SUITE_SINGLEUSERTS need to
be set so terminalserver will branch in the 'patched' branch of the simple
(termsrv.dll!CFullDesktopPolicy::UseLicense) license check.
So far I've only test it on WinXP SP2.
How the patch works - how did I create it.
Preparation:
get the source of this patch it contains some more info's
get debugsymboles for winlogon & termsrv
http://www.microsoft.com/whdc/devtools/debugging/symbolpkg.mspx
to add many useful label and comments to disassembling.
Get Antiwpa2 patch enable decrypt in options and open winlogon.exe
also press the apply button to remove self checks.
open termsrv.dll/winlogon.exe in ollydebug and look for references
(ctrl+n) to
Kernel32!GetVersionExW (ntdll.RtlGetVersion)
VerSetConditionMask
KERNEL32.VerifyVersionInfoW
to get near to the version restricting function - now your on your own...
In termsrv.dll look for symbols like
_fDenyTSConnectionsPolicy
LicenseModeInit
LCQueryAllowConcurrentConnections...
For live debug open process with commandline <WINXP>system32\svchost -k DcomLaunch
(Check commandline column in sysinternals process explorer to see it)
So what about the dot's
If it needs to seek to the beginning of some
certain function you to find some unique byte pattern (like a constant
or a sequence of command/byte) inside that function and then
move to the beginning and write the patch data there. Seeking with a byte
directly to the beginning is not so safe because all functions start
with the same commands. So if it seeks backward or forward to the beginning
I output dots as control. Normally this should be 1 or 2 lines - if there are
more it's probably didn't found the correct beginning (or beginning is already
patched) the patch is applied at some wrong location and result is corrupt
file.
AntiVirus alerts
Some AntiVirus detect 'WPA_Kill.exe' as HackTool, Trojan or
unwanted program. Well I don't know why the AV-Maker flag
'WPA_Kill.exe' this way, but it's definitly no virus or trojan.
Probably they don't like the fact that it modified some byte in
winlogon.exe or possibly violates M$-Eula or what ever. I don't know/care about.
Lately I want to install 'TS-Free-1.2.exe' on a friend's PC and found it
very annoy that the installed AVG-Virusscanner blocked access to 'WPA_Kill.exe'.
Also there was no easy to find an userinterface to disable this AV
and because there was only little time I saw the quickest way in uninstalling
that AVG crap via controlpanel software.
(Later I saw that this was good because AVG seems to have the weakest detection engine
(refers only to 'Wpa_Kill.exe') so probably it won't be better for real malware.)
I personly don't use any of this AntiVirus or Internet Security Babysitter software.
Windows is slow & anony enough so I don't need any addition annoying software panic brake.
(Just be caution when downloading keygen, cracks with emule or from so ads popluted
Crack-Site. Don't trust AV Prg but trust ya feeling. Well to get this watch all kinds
of files with an Accii viewer to 'feel' weather this is normal(uncompressed) code or
suspicious(compress/encrypted) code. Well that's how I started.)
Anyway most ppl just use AV-Scanners and as I see that this can be annoying
(or even wreak the system if the main patch is applied without to 'WPA_Kill'-prepatch and so winlogon.exe will crash...)
So I decided to do that update and change some pattern that AV uses for their recognition.
This is base on some list I found in a forum:
"AntiVir" -> Trojan/Agent.JH.7 Detection: Scans sfx-rar-archive comment (+Importtable)
"ArcaVir" -> <none>
"Avast" -> Win32:Agent-AKC Detection: Scans for "crackware2k@freenet.de...{ForegroundColor:&H00808081&}..."(size:0x20)

"BitDefender" -> Trojan.Agent.JH
"ClamAV" -> <none>
"Dr.Web" -> Tool.Wpakill Current version does not detect it.
"F-Prot Antivirus" -> <none>
"Fortinet" -> W32/Agent.JH!tr
"Kaspersky Anti-Virus" -> Trojan.Win32.Agent.jh Detection: Creates CRC of first 0xA70 Bytes of CodeSection

I made an improvement to the Terminal Services Patch v1.3 and I'am naming it v1.4
There are 3 improvements:
1) The patch no longer has to be executed from %systemRoot%\system32
2) The patch no longer triggers the Windows File Protection (WFP) warning.
3) A new key (AllowRemoteRPC) is added to the Registry, see the URL below:
http://www.pcreview.co.uk/forums/thread-2395421.php
How the patch works:
First 3 files (winlogon.exe, termsrv.dll, mstscax.dll) are copied into the current directory and patched there.
The WPA_Kill.exe is modified to patch winlogon.exe in the current directory, because in v1.3 the WPA_Kill.exe was hardcoded to %systemRoot%\system32 (very, very inflexible :/ )
Finally, a 3rd party 4KB utility (WFPdeprotect.exe) is used to avoid triggering the WFP when the 3 patched files are copied from the current directory to %systemRoot%\system32
