Ctrl-Alt-Del and win 7

Post by JonD »

I have InstantSupport installed as a service on remote computer... everything works except trying to log back in I can't get Ctrl-Alt-Del to initiate the login dialog. Is this a known issue or did I miss something?

AFAIK I've always been able to do this on XP clients.

My work around:

On the WIn 7 ctrl-alt-del opening screen, select the assistive icon and turn on the on screen keyboard. That got me past the ctrl-alt-del issue.... from them on I was fine.

If you're using 3.2 it's because cad.exe was removed from the project because it was not open source.
For sone reason I thought Rudi had figured out a different way to simulatesas, I'll have to look into that again.
Your solution will have to do for now unless you add cad.exe.

since vista and Rudi finally believe SAS is distributable function it available for uvnc and correctly catched with vista/2008 and 7/2008r2 by classic request system command of windows.
sas.dll required as separate and free for Vista/2008
sas.dll factory exist on system32 of 7/2008r2
sas.dll not exist and not required on xp/2003 as my knowledge

I found a solution that works by setting a Group Policy object to allow services to issue SAS commands...

http://kb.realvnc.com/questions/102/How ... +policy%3F

I tested this on Small Business Server 2008 with UltraVNC v1.0.9.5 64-bit

I've quoted this info below in case the original web page "disappears" one day...
There are two ways of setting the needed group policy setting, depending on whether the remote computer is connected to a domain or is a member of a workgroup. Please follow the appropriate section depending on your setup.

Domain procedure (change domain group policy setting)

If the remote computer is connected to a domain, the domain administrator can enable this group policy setting for subdomains or for the entire domain. Please follow these steps:

Important: Only a domain administrator can modify the domain group policy
Important: The domain group policy overrides the local group policy. If the domain group policy is not set, you can use local group policy setting mentioned in the next section.

1. Login to the remote computer as the domain administrator.
2. Click the Start Windows button, select Run, type gpmc.msc and press enter.
3. In the left section, select the desired domain, then right-click and choose Create a GPO in this domain, and link it here.
4. Right-click the new GPO and select Edit.
5. In the left section, please navigate to: Computer Configuration - Administrative Templates - Windows Components - Windows Logon Options
6. In the right section, please double-click on the Disable or enable software Secure Attention Sequence policy and click on Enabled.
7. Set the policy option to Services.
8. Click OK and close the Group Policy Object Editor.

You have now enabled the sending of Ctrl-Alt-Del on all computers that are connected to the domain you selected in step 3.

Workgroup procedure (change local group policy setting)

If the remote computer is a member of a workgroup or is connected to a domain with no domain group policy set, you should follow these steps:

1. Login to the remote computer as a local or domain administrator.
2. Click the Start Windows button, select Run, type gpedit.msc and press enter.
3. In the left section, please navigate to: Computer Configuration - Administrative Templates - Windows Components - Windows Logon Options
4. In the right section, please double-click on the Disable or enable software Secure Attention Sequence policy and click on Enabled.
5. Set the policy option to either Services or Services and Ease of Access applications.
6. Click OK and close the Group Policy Object Editor.

You have now enabled the sending of Ctrl-Alt-Del on the remote computer.
