Iam joining sky in the coming week and will be receiving their free router (G Router). I am currently using (Belkin N Router) due to the distance from my computers and interferance (eg , walls, 4 floors).
I understand that I cannot use my own router with sky because they have username & password built into router. I have heard rumours that these details can be extracted.
WHY ON EARTH DO SKY ONLY SUPPLY G ROUTERS

We have 694 units Cisco Catalyst 4507R plus E swithes accross the network. LMS 4.1 can discover it no problem however, i cannot extract inventory information for these switches. I get the this "Number of devices that do not have inventory collected data" on the report.installed System image file is "bootflash:cat4500e-entservicesk9-mz.150-2.SG1.bin"
i saw this supported version:
150-1.XO (or) 03.01.00.SG <<--- should i have the exact image or higher version will do? [Inventory Config and Image Management]
Reference: [URL]
Is the image installed on my switches not supported? seems like I have higher version.

I did nothing different to my computer. It was online fine and then an hour later when I came back, it wouldn't load any pages. I have a DSL modem and a wireless router that also connects another family member's desktop to the Internet. (As well as our phones via wifi.). The connection is fine on the other PC through a wireless adapter (both are desktops), and on the wifi the phones work perfectly so I know the modem and router aren't the problem. But even though my desktop says it's connected (not wirelessly, it directly connects to the router.), no pages will load. If I use chrome browser it eventually tells me this webpage is not available regardless of which page I try to load, or sometimes it's telling me no data received - unable to load the webpage because the server sent no data. Yet oddly a couple of times after forever it seemed to half load a couple pages. Internet Explorer just keeps trying to load pages forever with blank white page as a result.

I have one server-A(windows 2008) installed one application called"host front" which gives athentication to connect Linux(mainframe console)server(SERVER B). These 2 servers are bihind the firewall.If one internal user who has the athentication to logine server-B ,tried to login server A,will get the" username and password"screen and once they enter the username and password ,will get the server-B screen.But if somebody try to connet via MPLS(we need to test MPLS site customers) from outside via ASA 5540 ,to server-A will get the "username password" screen and once enter the credentials,after 1 minitue will get error"http server faild to send datas to the server" and will not move to server -B screen.Where do you think is the problem?

I am setting up an offsite storage server for work at my home which will sync a few times a day to grab data and i wanted to ask about options for encryption or if i should worry about it.i am going to be initially dumping about 1-1.5T worth of data, with then maybe a couple of gigs a day added of new stuff.i am going to use server 2008 r2 as i am also doing a read only DC/AD for this system to give me and offsite controller just incase also.
I was thinking encryption for one more level of safety just incase something happened to the server, like theft or something but not sure what could reliably handle that much data ? System is only a dual core e7500 with 8G of ram, i have 2x500G SATA in raid 1 for the OS and 4 x 1T drives in raid 6 with 2 more coming.

How can I tell if the ATT Data Service on my iPad is going through an ATT Carrier Grade NAT router or proxy server? Why I can't tell.
1. iPad does not have an interface that shows the assigned address on the Data Connecton or access to any terminal commands.
2. The reported ATT (Cingular) address is 166.147.103.208 if you use a What-Is-My-IP type of service. On a Verizon (not ATT) iPad I can ping all the way back to the iPad and turning the iPad off stopped the Ping Response . . . but there is no answer when I ping the ATT iPad 166.147.103.208 and Trace Route to the iPad stops answering at the border of the ATT network.
3. If I make a page request on an IIS web server from the ATT iPad, the web server logs 166.147.103.208 (see above) as the source address and logs the iPad as the source device, but 166.147.103.208 could still be an ATT proxy, not the iPad because some NAT routers change the source IP address to themselves.
We want to use an ATT Hotspot as the the permanent always-on home internet service where there is no other option (except satellite). We need dynamic DNS at the home, and that requires a routable public address on the ATT-hotspot. We are guessing the iPad and HotSpot would be using the same ATT network.So how can I tell if the iPad has an ATT address that can be reached from the internet (no proxy's or carrier grade NAT routers)

We have a quad port NIC on our Dell server.I want to take all 4 ports and plug it into our switch and have it all go to the same IP of the server and just have to share the data load in/out.Do I need to configure anything to do this?

I was upgrading the OS [c:] on a DELL Poweredge 840 server from Win2k3 server to Win2k8 R2 server using the Dell SMTD DVD to prep the install. This has always worked in the past without destroying the data partitions. (I have now found out this only works properly if the OS is on a RAID 1/0/10 and the data on a RAID 5)
In this case the OS & Data were both on RAID 5 & the Dell tool reformatted (quickly) or maybe reset the partition table so that it looks like one big drive. I noticed this once I got to the install screen for Windows 2008 R2 and shut down the system.
Are there any utilities that can be run from a bootable CD/DVD that can undo the format on the RAID 5 set or else let me browse & recover the data on the various partitions?

anyways here is my concern, we have a DHCP server in our company (HOTEL) and the Computer wont turn on, the computer is Compact Proliant Intel Inside Pentium Pro Processor OS Windows Server 2003, this Computer is so old. they been using this for 12 yrs and they didn't upgrade... now its dead.
since this Computer wont turn on, all of the computers cannot access in the internet, so for the meantime this is what I did... from the modem to router, I configure the router as a STATIC IP and I enter the IP address provided by our Internet Service Provider after that all of the computers form the hotel have internet connection.
now I'm planning to build a new PC and set up a DHCP server but I don't know how and where to start

I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues. For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.

My Windows xp computer can't connect to the DHCP server correctly and thus can't connect to the internet. It is connected through an Ethernet cable to a wireless router. All other computers on the same network connect fine to the router, both wired and wireless.This all started after I left my computer alone for a few hours and came back with it not coming out of idle. After shutting it off and turning it back on, it would not connect to the DHCP server.It assigned me the autoconfig address 169.254.189.73 because it couldn't connect to the DHCP server. I even tried a static IP but even that wouldn't fix it. I have tried the same ethernet cable in another computer and it worked fine so I know that it is because of my computer.I have tried renewing and releasing the connection using ipconfig in the command prompt but that did nothing. The settings are all the same as the other computers running through the same router. I have tried shutting down all the other computers and reconnecting the trouble one but again still nothing.The last thing I'm not sure about is the network adapter driver. I have reinstalled it but I'm not sure if the driver is correct. I have an NVIDEA nforce 10/100 Mbps Ethernet adapter. I attempted to reinstall but I'm not sure I selected the correct generation when I downloaded the driver installer. My computer says nothing about the generation of the adapter so I just chose the newest generation. My adapter is integrated in the motherboard.

I have a machine with Windows Server 2003 running an Exchange Server in a office with 5 workstations attached. The server is being used for a basic outlook calendar across the various workstations, nothing major. Our current ISP provides us with a Static IP address. The party that installed and configured the server set it up to run the DHCP server on the server PC itself. As in, the machine running windows server is also running a software DHCP server for the entire network. THE SETUP: As of right now we have a wall port (internet access) with a cable running to a 8 port unmanaged netgear switch that has cables hooked up to the 5 workstations as well as the server itself. Pretty simple.THE QUESTION: How do I configure the ISP static settings on the DHCP Server portion of the Server PC? We may be getting a new ISP with a dynamic address OR a new static address. WHAT I'VE TRIED: I've tried configuring the IP address on the Server PC the way I would via the NIC adapter settings but it already has a internal IP address from the DHCP Server running on that PC so changing that was no good.

I'm using 2003 server for DHCP settings. I don't want some computers to get ip address automatically but if they put manually ip address, it's ok, they can connect.How it can be done?I mean when those computers try to connect for wireless, they should not get any ip address (so internet) until they put manually ip address, default gateway and dns server.

I recently reset my Quidway WA1003A modem from Huawei and ever since, the radio button for the server settings under DHCP configuration is at OFF whenever I start up my computer. So if I try accessing the internet via wi-fi on my phone, I'll have to manually change the radio button by opening up 192.168.1.1 through the browser on my computer each time. I never faced this issue prior to the reset. It used to somehow always be saved as ON.
