UltraVNC

Hi, I'm jumping in the thread because I once find out that if the computer you want to take control to has been "secured" by removing everyone and administrators from the "Access this computer from the network" user right (see in gpedit.msc), then MSLogon II will fail but MSLogon I will succeed. My ...

This is REALLY awesome ! Go on Rudi make all kinds of crazy new functionalities so that UltraVNC stays light years ahead of other VNC incarnations ...

I've noticed 2 things with the wallpaper removal: - if you connect to UltraVNC when a session is not opened on the server, the wallpaper is not removed. Close your VNC viewer, reconnect to the server and the Wallpaper is now removed - UltraVNC only removes the "classic" Wallpaper not the Active ...

Ok I found what was wrong ! The PDC Emulator of the AD domain was in a kind of coma. After reviving it authentications to UltraVNC work again. So old mslogon relies on PDC Emulator whereas new mslogon doesn't. Wish I could use the new one, it's soooo much faster !!! Thanks again Marscha and sorry ...

Thank you for your quick answer. I've got a problem with the new mslogon, it doesn't work on some hardened computers where I remove everyone from the "Access this computer from the network" right. I just did the test and the new mslogon works where the old one doesn't. With old mslogon, on a W2K ...

Hi Marscha, Starting today, UltraVNC on all my computers in the Active Directory domain won't accept to authenticate domain accounts which are also local administrators of these computers. The same domain accounts are still indeed administrators of the computers because I can list the contents of ...

Also make sure that they don't have the right to stop the service from the MMC. Personnaly I used SUBINACL to set custom rights on the winvnc service to allow the "Power Users" group members to start the server (in the eventuality it would stop) but not to stop it. I also activated the automatic ...

I was always told that snapshoting drivers installations was a really bad thing to do ... However, having the exact same hardware on all your computers could help this MSI installation to succeed. Can you report on your success rate ? I also built an UltraVNC MSI from scratch that install the ...

Thank you for your answer !

By the way, it works perfectly in MSLogon II, checking only View in the group ACL permits only a viewing of the remote computer (good work Martin).

Hi, Leaving aside the cool MS Logon II and testing the "old" MSLogon. What is the meaning of the Group 3 = Read Only ? I was expecting that if I put someone in this domain Group, when connected to the vnc server he'll have view only right (no click, no keyboard) but it's not what I'm observing. It ...

Martin,

Thanks for shedding light on this issue. I guess I'll have to revert to this workaround if I want to use the greatness of MSLogon II !
Nice job anyway.

Take care,

Marc

Hi Marscha, I've got a problem that's causing me a few headaches even if I'm able to find a workaround I'd like to have a technical explanation from you. In my company we have a rule that enforces heavy securing for laptops. One of this security parameter is to remove any access from the network to ...

Just did the test, it works ! Connected to UltraVNC with a forest root domain account with the user@rootdom syntax. This user is in a global group in the root domain, I put this global group in a local VNCACCESS group on my workstation which is in a different AD domain from this user. The OS on the ...

Thanks Marscha, it works now.

Best regards,

Marc

Marscha, Quickly some feedback on what I tested: login with user@dom : ok login with dom\user : ok login with user in local workstation group : ok login with user in domain group nested in a local workstation group ok Didn't have a chance to test cross domain authentication but I'll do it. Regards ...

Hi Marscha, First of all I'd like to congratulate you for putting up this new authentication method for UltraVNC as it is overall more clean and faster than the old method. So far I found one minor bug in the ACL importation procedure. I can export the ACL with the MSLogonACL.exe /e command and get ...

Will tweak setupdrv, and remove the messageboxes for silent installation. Great news ! Thanks Rudi !!! The AutoIt solution wasn't good enough indeed... Can you also check if there are problems with working directory when launching "setupdrv.exe -install" ? It looks like the install fails if I don't ...

setupdrv -install setupdrv -remove Perhaps you missed the parameter Hi Rudi, I was aware of these two command line options but they are not silent at all. A box pops up saying that the driver will be activated on reboot. Could it be possible to add a silent option to both install and removal ...

I have been spending the last week tweaking ultravnc and fastpush... my only issue is the video driver... I can copy the two files over to the 'server' computer in the script, but then what? Any ideas how I can install the driver remotely using shell commands? Does anyone have any ideas on how this ...
