We had he same issue, but I found a work around (in our case at least) by making sure the tv/monitor/projector/smartboard is powered on BEFORE the device plugged into it. If the Laptop or PC is powered on, then connected to the AV device, then the AV device is powered on, we get the same as you. In our case it can sometimes be solved by removing HDMI / VGA lead and plugging back in then re-selecting source at AV. We also had a related issue that when Powerpoint was in presentation mode and the teacher froze the screen (via freeze button on remote for projector or smart board) the screen went black. The above solution of screen power on first, then connect AV cable fixed this issue also.

Hi All, just for completion and in case anyone searches this thread in the future, Ghanel provided me with the solution. I copied the existing config file from a working switch by connecting a serial link via Putty and using the command: show running config I edited the necassary names, IP's etc on the config and connected Putty to the new switch and pasted the config in. All the settings from the old switch have now been applied to the new one and I'm able to log in now via the web interface to do a bit of fine tune tweaking to the port settings. Many thanks for your help guys, it's much appreciated.

Yep, show vlan shows there are no Ports assigned to Vlan 10. I've PM'd you a running config of a current working switch and the new one. Thanks for your time on this, it's been consuming me for days now. It's much appreciated. *Edit* I tried PM'ing you but when I pasted the config all the spaces got removed. I didn't want to send you a mass of concatenated text.

Thanks both, I made progress. Yes, I'm connected via putty through the serial port. I need to set this command up before I can get web access to the switch it seems. I configured Vlan 10 as ghanel suggested, this worked, and I did need to save it - for Dell this turned out to be the command "do write" I am now left with the following vlan IP interface: Vlan 1 UP 0.0.0.0 0.0.0.0 DHCP Vlan 10 DOWN 10.10.1.9 255.255.0.0 Manual This is the same as the other switches now except for the fact that the state of Vlan 10 is down, and I can't figure out why, and can't seem to enable it. I can't find a command to enable it, so there may be a connection issue - the gigabit cables are plugged in and lit up on LNK but not ACT. I can't connect to 10.10.1.9 via a web browser either, presumably because it's down.

Hi All, Does anyone have experience in setting up a Dell N2000 series via the Command Line Interface? I've got 8 identical switches and recently added a 9th to expand the network. The other 8 were installed by a company we no longer have contact with. I've followed the instructions as far as I can go, but have hit a wall when it comes to getting the switch to communicate with our main core switch management system. The original 8 switches have all been setup with the following VLAN configuration: VLAN 1: IP address: 0.0.0.0 IP Mask: 0.0.0.0 Method: DHCP VLAN 10: IP address: 10.10.1.1 Mask: 255.255.0.0 Method: Manual It looks like the switch can be setup with a double VLAN mode. However, when I follow the Dell auto config wizard to set my new switch up, dual VLAN mode is not an option. All I can do is setup VLAN 1: VLAN 1: IP address: 10.10.1.9 Mask 255.155.0.0 Method: Manual I need to configure it to have the same double VLAN config as the other 8 switches above, with VLAN1 on DHCP and VLAN 10 on Manual, but the 2500 page CLI config manual is sapping me of a sense of humour. Can anyone point me to some useful CLI commands I can use to setup this double VLAN mode? I can connect to the CLI via terminal no probs, I just need to figure out the correct commands. To get the VLAN's looking like this: VLAN 1: IP address: 0.0.0.0 IP Mask: 0.0.0.0 Method: DHCP VLAN 10: IP address: 10.10.1.9 Mask: 255.255.0.0 Method: Manual Thanks in advance, Kieron.

CHU - would you mind sharing with me how you did this. We use Impero too and I've been asked to create a CA group. Doing it through AD is possible but painful. Do exam boards have any guidance on how sysadmins are supposed to do this or does it just happen?

Just for information, we've been hit with this problem now. Post - login. It started occuring when we upgraded Impero from version 5420 to 5436. At the same time, I noticed that Impero Server was not pushing updates to client machines so I also ticked this on. Our users also have a roaming profile. Turning Impero off solves the problem. In the first instance I'm going to restart the Impero service add userinit and explorer as expalined by timbo to list of exceptions and see what that does. Then I'll try using the remove cache dump script posted by Steve if that doesn't work and will report back.

I still can't get this to work, I've tried various combinations of merge, replace and enforce, but all I succeeded doing was removing my own admin permissions to access the C drive! Our OU has several other GPO's in it. I'm beginning to think that there is more than one GPO that is restricting the access to C drive and Control Panel. I'm going to contact the 3rd party who set this up and see what they suggest, but thanks for all your help. I learned a load about settings I'd never before considered and am better equipped now to explain what I want.

So Tom, are you saying I'm better off creating a new clean GPO with just the changes to allow C drive and control panel and set this to merge with the Student GPO? I was afraid that if I did this, any other "not configured" items in the new loopback GPO would override the other settings in the Student GPO. I want to retain the other settings in Student GPO but just override C drive and Control Panel. I've tried this out and set to replace at the moment but it doesn't seem to be taking effect. When the little darlings go home I'll try it out with merge. Thanks again.

Thanks both of you - Loopback processing is exactly what I need to apply in this situation. Looks like I've got a bit of reading to do but it looks like just the ticket.

Hi Guys, Our AD structure and GPO's were setup by a third party company, I'm new in the role and I'm trying to get my head round how everything is connected just so I've got a better understanding myself. I've got some experience of GPO's but I'm no expert. We have a setup where staff can access C drives and Control Panel but students cannot. That's fine, and I'm happy how that all works in the GP structure we have two different GPO's that dictate which domain users can access what. However, I am wanting to allow access to the C drive and Control Panel for students in one particular IT suite. The PC's in the IT suite already exist in their own folder in our AD, so it's a simple case of dropping the correct GPO into their folder in group policy management. Here's what I was going to do. Copy the Student GPO which resides in root users folder, modify the GPO to allow access to the control panel and C drive. Add this modified GPO to the relevant IT suite folder in GPM and bingo... However, I tested this and it didn't work. Students in that IT suite still have no C drive access. Do the GPO's in the root user folder override any other GPO's in daughter folders? Thereby overriding my modified GPO? What is the best way to add a GPO so that students can access their C drive only in a specific list of PC's? I hope I've explained myself sufficiently. If any of you are wondering...yes I could ring up our 3rd party company who set this up but that's not the point I want to learn myself! I've got so far but am now stuck. Many thanks.

Hi Guys, I've generated guest passes using Ruckus Zonedirector many times in the past and experienced no issues, except today when I generated a new guest pass for unlimited users and go to confirm after this stage: it returns me to the Ruckus login page and doesn't generate the temporary pass. Any Ideas? I've tried logging in using 3 separate users I know have access rights to generate guest passes and it does the same on all three accounts. UPDATE = I repeated the process but instead of generating a pass for unlimited users, I generated one for 10 users and it's worked. So I guess there's a problem with generating a guest pass for unlimited users?

The winter skies here in Scarborough take on a whole new personality in HDR. I like to mess about with HDR quite a bit, and yes sometimes I overcook the effect. But I like it

Agree with FN-GM, we use Google Classroom as a VLE. If we need to expand on this we can use Blogger or Google Sites. I found Moodle time consuming considering we were only using it as a glorified file repository.
