Thanks Norphy. This has been driving me nuts....and here I was updating Java to see if that would help...ha! I did as you suggested and it now allows the web interface to load...not without the warning of danger Will Robinson of course! I just clicked run and I can configure to my hearts content. Thanks again and to Timbo too.

Hi, We have a couple of HP Jetdirect 170x boxes around the school connected to a HP 4200 and a HP Plotter. I was just trying to log in to one to reconfigure its IP address when I moved the printer's location and I can't get in. The four panels you normally see when connecting to the web interface begin to load. I see the Java logo and the spinning circle and then I get four error messages (all the same) for each panel. The error states: Application Blocked by Security Settings Name: linkTabs Location: http://ipaddress of box Your Security Settings have blocked an untrusted application from running I have to click ok four times and the page loads with "Error - Click here for details" in each of the panels. When I click that I get the same error message and a details button. When I click the details button I get a Java Console load up with the following text: Java Plug-in 10.51.2.13 Using JRE version 1.7.0_51-b13 Java HotSpot™ Client VM User home directory = C:\Users\Kevin This is what I get when trying it from my laptop which is Windows 7 and not on the domain in the school. I tried using Firefox 26, Chrome and IE 11. I thought it was something to do with Windows 7 or the fact I'm not on the domain (don't remember this being an issue before) so I tried it on a Windows XP machine that I had just formatted and re set up. It was fully up to date but I get the same error again even though I'm logged in as an admin. And again I tried the usual three browsers. Does anyone know if this is a browser thing, a Windows thing or something else configured on the network or the server? Thanks for any ideas Kevin

Hi all, I am trying to deploy images to a number of computer rooms here in the college. I have captured image from one PC in each room that is fully up to date and set up. When I PXE boot any PC I choose my Win7 install boot image and then it lists all the images I've captured over the last week. All except one. The one that is missing is for the sound engineering computer room. A few years back they had issues with scratching on many of their recordings so the tutor discovered that if you set the computer back to being a standard PC instead of ACPI computer (click plus beside Computer in device manager, change the driver to standard PC) then this solves the problem...which it did. The pain is that when you shut down the PCs they sit there saying "it is now safe to turn off your computer". Anyway, I found an article from Microsoft (An ACPI APIC UP HAL operating system image cannot be deployed if a Windows 7 boot image or a Windows Server 2008 R2 boot image is used in the deployment process) talking about problems with the window7 boot.wim file not displaying non ACPI images or something to that effect. I downloaded the hotfix, its a self extracting zip/exe file but when you run it says that its part of a mutildisk fix and to insert the second disk?! The instructions say to extract a cab file but as the downloaded file doesn't extract properly I can't get to that cab file. Is there anyone out there with the same problem as me or even a solution to extracting the hotfix correctly. The image file is 50GB as all the music software, plugins etc were installed before capturing the image. The deployment server is Windows Server 2008 R2, the boot image was taken from a Windows 7 disk but I tried one from a Windows 7 disk with SP1 as I read somewhere that the problem was fixed in the that wim file but still the same problem. The machine that was captured is a Windows XP SP3 machine and I tried to deploy the image back to the original PC and to a few others around the building in case it was a HAL issue but I'm at a loss now. If you need any further info let me know, any help is much appreciated as I'm at hair pulling stage now Thanks K

Hi guys, Thanks for all the replies. Some seem to think its handy but most seem to think its not necessary. Are there any disadvantages to doing it? All those who said its not necessary on clients never really gave a disadvantage to the set up, merely that it was not needed. Thanks K

Yep, I set the DHCP reservation in the DHCP via the MAC address of the device and then leave the PC to automatic so that it requests an IP address from the server but as there is a reservation the server will always give it the same address. Switches, servers, printers are set up at the device with manual static IP addresses.

Hi all, From previous help you have given me I see that some people start off by saying "if you have static IP addresses on all the PCs in the computer labs then....". I was just wondering what the advantages to having static IP addresses are and are there any drawbacks to setting the PCs to have the same IP address all the time. Being a self taught server maintenance guy I only have experience of Group Policy when I've needed to do something specific rather than having trained in it and knowing it in a general sense but I would imagine it would make things easier in relation to GP? Am I right in that assumption? I had the MAC addresses for 90% of the PCs in the college from another project last year so I set about creating reservations in the DHCP management console. I have done this for 180 of the 240 PCs so far and I've tested a couple of labs and they all take the IP address I set up for them. The VP here in the college wants me to set up VPNs which I have no experience of but will research over the coming months. Would static IP addresses be beneficial here too? Basically, what are the pros and cons of Static IP addresses through DHCP reservations? Thanks for any insight. K

Thanks to all again. I forgot to let you know how it went. I implemented Michael's suggestion of stopping the browsers from running and it worked perfectly. As I mentioned above there are only three browsers installed and the students don't have access to install anything else so that worked for me. I was then able to quickly turn off that group policy after the exam on the Saturday morning so all would be ready for normal classes on the Monday. Quick and easy. Thank you people.

Thanks to all who posted. Appreciate the time ye took. I'll let ye know how it goes.

Hi TomC, excuse my ignorance but what is TMG. Is it third party software or something built in to Server 2008? Thanks for the info

Thanks Davitt, that sounds like and interesting solution and not something I was aware of. I might give that a try the next time but as the GP solution from Michael is something I'm a little familiar with I'll try that for now. Thanks for the suggestion and I'll let you know how it goes if I get around to trying it.

Cheers Sted, Its something I thought of alright but I would rather something that is turn on and offable to quote a famous turtle so I'm going to try Michael's solution. Plus at 4 pm the day before the exam a quick solution through GP is handiest for now. thanks

Thanks Michael, sorry for delay in thanking you, had a busy week and only getting a chance to implement this now. I will try your suggestion of preventing browsers from running. I know there are other browsers but those three are the only ones installed and as students can't install anything I think that should cover it. I'll let you know if it works. Here I am at 4pm trying it out...typical

Once again I need your zen like experience people. There are 8 computer labs/rooms in the college. We have a Server 2008R2 domain controller for AD, DHCP and DNS and Untangle Lite running on another HP server doing the filtering. The Untangle boxes takes a feed from the internet router into one network card and is connected to the main network through a second network card. There is an exam on Saturday morning and the students will need to save data to their home folders for later collection by the teacher and they will also need to print to the lab printer which is done through the server. However, they can't have internet access. Is there a way through group policy to isolate this computer lab so it doesn't have internet access but does have normal domain/network access while leaving the other labs alone? This is a part time course exam so it is the only one on in the college at that time. I know I could just unplug the router but the daytime/fulltime exams are coming up in a couple of weeks and I will have to do the same for some of them. I read somewhere else that you could change the gateway that the server puts out in DHCP but this would affect all computers....or is there a way to change the DHCP settings for one set of computers? I didn't think so but then again I'm not qualified in servers, just teaching myself as I go along and certain things are needed. I also read somewhere that I could use GP to put a random proxy into IE but Firefox may be on some of the PCs or Chrome so if I change the policy for IE would any other browser automatically pick up on that? Any ideas or pointers would be appreciated. Thanks K

I know this thread is old but it helped me out today. Time was wrong on one PC and that solved the access denied issue. Cheers Mr Bios K

Hi Matt, Thanks again for getting back to me. Wasn't expecting a reply so wasn't checking. Would you believe I did pretty much what you were suggesting. I used cacls not icacls though. It worked anyway so all sorted. Thanks again for your help throughout the issue. Once again the edugeek site has saved me a lot of reading and hair loss K
