This is a pretty weird requirement I believe. If any of you can help me with anything it would help me a great deal.
As the topic says, I need the windows machiens to auto logon on reboot. The standard method of registry tweaking is
not allowed to me as it exposes the password in txt format.
On every monday morning, when the server reboots I login to the console and interactively login to all the servers.
There are about 25 of those and obviously I would like to automate this process. So, can you guys suggest me
anything? I think the best thing would be to put a script on the server which will login the user on reboot and
not expose the password in text in registry. The password can be stored in text in the script as it is allowed.

Alternatively, if I am connecting to the server, is there any way by which I can send the user name and pwd to
the server so that it logs in?

Hope someone helps me with this one. :)

Thanks!

Status: offline 		Hi guys,

thanks a lot for the reply. I have thought of one more method which I think should be possible. I would like to know more about it from you guys.
I know that using vbscript we can edit the registry contents. For autologon you need to tweak the registry contents a bit. So, I have thought of writing
a script that will run one minute before the reboot (my reboot is a scheduled task) and change teh contents of registry. Following this, on reboot
a new script will run to remove the contents of the registry and lock the screen. Can any of you tell me if this sounds possible? In the sense, can vbscript
edit any contents in the registry?

Also, I have found an ADM file which kind of does the auto login.
Does anybody have an idea about teh ADM files and how one can use them?

They are used in conjunction with Group/local policies to alter registry settings.
It is certainly possible to do what your wanting using Policies and ADM files, but if you have no experience at all with ADM files, i would stick with the VBS.
An ADM file is basicaly a list of settings. It consists of several bits of information, one being the part of the registry affected,  but you also need to tell it how it will be read by the policy editor.
Eg.. what category it exists under (eg user or machine setting) then where it the policy editor it can be found... eg.... User Configuration > Administrative Templates > Windows Explorer etc
also it needs strings specified for what us to be displayed by the policy editor GUI, and then the actual values themselves, presented in the appropriate manner.. eg checkbox, dropdown list radio button etc.

as for how to use them.... you would opejn up the policy editor ... right click on the administrattive templates folder under the approiate section... (either computer Configuration or User) and the Add a template file (adm file)

There are lots of examples of how to make your own adm files on the net... butas i said before.... if your not familiar with them, i would stick with VBS.

Status: offline 		here's another idea...

you could use a combination of this software.. (logon.exe)

http://www.softtreetech.com/24x7/archive/51.htm

with something like psExec to remotely auto logon all the PC's via a script.

eg a batch file with the folowing commands..

psexec \\server1 Logon.exe -u Username -p yourpassword
psexec \\server2 Logon.exe -u Username -p yourpassword
psexec \\server3 Logon.exe -u Username -p yourpassword

better still use vbs and have it prompt you for the password.. and not have to code it anywhere!

Status: offline 		I like Parabellum's idea. If it works. That way you are as secure as you can be...
No password in the registry whether encrypted or not. No password embedded in a script.
The only problem I have with this solution is PSEXEC will send your password across the network in plain text.
