clone virtual machines and copy their own unique vmdk image to folder

  1. create the new VM choose custom settings
  2. select the existing Virtual Machine Image (base)
  3. finish creating
  4. ssh into box
  5. copy vmdk using: vmkfstools -i <source> <destination> -d thin (NOT the data file -flat.vmdk)
  6. when copy is complete, using vi, edit .vmx file in new VM directory. Point the data store (hdd file location) to the new copy that is now in the same folder
  7. start up VM
  8. shut down vm, double check and make sure store is showing in the correct location. Virtual Machine > Edit Settings > Hard Disk > review Disk File

notes: until the virtual machine is started for the first time, the Disk File location will still show as the prior location.

i.e.
/vmfs/volumes/511a8041-9e4d7168-27f2-001cc46b0828/Windows XP Pro x32 - Outlook 2003_2 # vmkfstools -i /vmfs/volumes/
datastore2\ -\ RAID5/Windows\ XP\ Pro\ x32\ -\ Outlook\ 2003/Windows\ XP\ Pro\ x32\ -\ Outlook\ 2003.vmdk /vmfs/volumes
/datastore2\ -\ RAID5/Windows\ XP\ Pro\ x32\ -\ Outlook\ 2003_2/Windows\ XP\ Pro\ x32\ -\ Outlook\ 2003_2.vmdk -d thin

Windows 7 remove RDP restrictions - no download required

NOTE: This never worked right for me. I never tried the exe offered to perform this task and analyzed the results, maybe later on.
Requirements:

  • hex editor for windows
HxD http://mh-nexus.de/downloads/HxDSetupEN.zip
  • be directly connected to the windows client, not a remote desktop session.

Stop remote desktop services

  • Start > Run > [type] services.msc > [click] OK
  • Sort Services by name and find "Remote Desktop Services" > [right-click] Remote Desktop Services > [select] Stop > if any prompts appear about additional services that will also be stopped, [click] Yes

Backup termsrv.dll

  • Start > in "search", type cmd > [right-click] cmd.exe & select run as administrator
  • type: copy C:\windows\system32\termsrv.dll C:\windows\system32\termsrv.dll.bak
  • check to see if termsrv.dll also exists in C:\windows\system32\dllcache\ and if so, repeat the same steps as above, but make sure to change the path (C:\windows\system32 > C:\windows\system32\dllcache)

Determine termsrv.dll version and obtain HEX replacements

Note: You'll need to determine the version of your termsrv.dll in order to get the HEX replacements before you can patch it.
First copy termsrv.dll to a location you can edit.

  • Start > in "search", type cmd > [right-click] cmd.exe & select run as administrator
  • type: copy C:\windows\system32\termsrv.dll %userprofile%
  • Open HxD > File > Open > C:\Users\[your profile name] > [select] termsrv.ddl > Open

Looking at the text interpretation of the HEX, you should be able to find something like "F.i.l.e.V.e.r.s.i.o.n" followed by the version of termserv.dll.
I found mine near the bottom of the file, next to this HEX:

69 00 6C 00 65 00 56 00 65 00 72 00 29 00 01 00 46 00

My version turned out to by 6.1.7601.18637

From here you'll need to search google and blog/forum posts to see if someone has posted the HEX replacements. The search term I used to find mine was "windows 7 patch termsrv dll 6.1.7601.18637"
In the very first link, in the article comments, someone posted the HEX replacements for my version.

Patch termsrv.dll

Hopefully you were able to find the HEX replacements for your version.
Since in the previous step we copied termsrv.dll to a location we can edit, lets go ahead and update that file.

  • Open HxD > File > Open > C:\Users\[your profile name] > [select] termsrv.ddl > Open

Note: your HEX replacements will probably be different than mine, but i'm including what I did for my version so you have a clear understanding on how to modify your termsrv.dll.

For Windows 7 x64 termsrv.dll 18637 64bit
Find: 8b 87 38 06 00 00 39 87 3c 06 00 00 0f 84 eb c2 00 00
Repl: b8 00 01 00 00 90 89 87 38 06 00 00 90 90 90 90 90 90

Find: 60 bb 01 00 00 00 c7 44 
Repl: 60 bb 00 00 00 00 c7 44

Find: 50 01 76 1b 48 8d 15 49
Repl: 50 00 eb 1b 48 8d 15 49
  • With termsrv.dll open in HxD > Search > Replace > [select] Datatpe to "Hex-values" > [select] Search direction to "All" > [select] Prompt on replace.
  • In the Search for field, input the original hex value you are trying to find.
  • In the Replace with field, input the new hex value.
  • [click]OK

Repeat this process for all Hex strings (generally 1-4)

  • File > Save As > "termserv.dll.patched"

Replace termsrv.dll with patched version

  • Start > in "search", type cmd > [right-click] cmd.exe & select run as administrator
  • type: cd %userprofile%
  • type: copy .\termsrv.dll.patched C:\windows\system32\

Regedit

  • Start > run > "regedit"
  • goto HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\Licensing Core (or HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\RCM\Licensing Core)
  • create a new DWORD key "EnableConcurrentSessions" without quotes and enter its value as 1.


  • goto HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
  • create a new DWORD key "EnableConcurrentSessions" without quotes and enter its value as 1
  • create another DWORD key "AllowMultipleTSSessions" without quotes and enter its value as 1 too.

Allow Users remote access

  • Start > [right-click] Computer > [select] properties > [click] remote settings
  • Under the Remote Tab, Remote Desktop group, [select] "Allow connections from computer running any version of Remote Desktop (less secure)"
  • [click] "Select Users..."
  • [click] Add > type in the user's name > [click] "Check Names" > [click] OK x2

Note: if your computer is on a domain, you'll need to create a batch file to run on startup every time the machine reboots. See this article but by mindful of the registry paths, you may have to modify the batch file to match your registry paths. Now right click on My Computer and go to Properties->Remote. Enable allow remote connections and select the users for whom you want to enable Remote Desktop Services.

Start remote desktop services

  • Start > Run > [type] services.msc > [click] OK
  • Sort Services by name and find "Remote Desktop Services" > [right-click] Remote Desktop Services > [select] Start

Restart

Restart your computer.
