"server not found" with one ip address but ok with vpn ip

Windows 7 For the last few days I get "server not found" message when I try to access many sites (including Mozzilla help). This happens with ie also.However when I use a different IP (via my VPN) everything is OK.
What is going on?

Server not found - approx one in three times

For about the last five weeks I have been encountering many delays in getting to web pages and when I do download files they are taking an inordinate amount of time to go through the "download and then open process".
The server not found issue seems to occur on about one page in three. When it has failed (after about 15 seconds) I usually have to try again twice more before it loads. Clearly there isn't an address problem or it would never load. I have been through the Helpdesk route and they cannot find a fault. I have tried lots and seemed to make the most progress in eradicating the problem when I uninstalled NetProtect Plus and reinstalled it. I then had no problem for about three days and after that the fault just seemed to worsen - back to its original state.
As I said. No problem at all until a few weeks ago. Problem temp disappears after uninstalling and reinstalling NetProtect Plus.
Any (good) ideas please? Getting seriously annoyed.

I've experienced a very similar, if not the same problem. I am running Windows XP and the problem seems to have started to happen on upgrading to IE8. When I close down the computer indicates that something to do with MacAfee (i.e. NetProtect) is 'not responding'. I don't know if this is linked to the problem or not but indicates to me that I have a software conflict somewhere! Can anyone help? Should I revert to IE7? Thks

HT1689 In a household with one email address but 3 or more devices, we have trouble playing games like Gems, Draw Free etc. with other people. How can we solve this easily?

In a household with multiple devices but one email address, we have problems playing games such as Draw Free, Gems, etc with others. What is the easiest solution?

Each user should have their own icloud account, otherwise they end up getting the same emails, contacts, calendars, notes, reminders, etc. - usually not what you want. But if all have been sharing the same itunes ID, keep it that way, you can have different IDs for itunes and icloud.
If you already have another icloud account, and want to set it up on a device, then go to Settings>icloud, scroll to bottom of screen and tap Delete Account. This only disconnects the device from that account, no data is lost on icloud. Then enter the account ID that you want to use.

WLC 2504 problems with one IP address range

I am having an interesting issue configuring a new 2504.
How it is setup:
Port 1 management with vlan tagging on vlan 111
Port 2 trunking with ap-manager2 on vlan 3, 102 on vlan 102 (Not ap-manager), and 1001 on vlan 1001.
All of the vlans have distinctive and unique IP ranges. Vlan 111 is running 172.16.128 /20, 102 is 172.19.252 /23 and vlan 1001 should be running 172.17 /16.
Here is my problem. I can setup all of the dynamic interfaces on the appropriate ip ranges, but for some reason when I configure the 1001 vlan dynamic interface with the /16 address space, I lose connectivity to the GUI managment interface. I have to go in through the CLI and remove the interface or change the IP range. I have tried other /16 address space on that vlan and do not have a problem with them. the 172.17 space appears to be the only one that will not work.
I have attached the config from the controller (Minus some site specific stuff like the SNMP community and wpa stuff.) The config is using a 172.20 /16 right now on the 1001 interface so that I could get into the controller and download the config. It should be 172.17 /16. The acutal IP info should be 172.17.4.253 255.255.0.0 172.17.0.254
My computer is on the 1001 vlan and I have verified the IP is not in use and am using the same subnet, gateway etc as I am trying to configure the wlc with.
Switch config:
Port 1 is plugged into g0/2 with the following config
interface GigabitEthernet0/2
switchport trunk allowed vlan 1,3,102,111,1001
switchport mode trunk
spanning-tree portfast
Port 2 is plugged into fa0/47 and just has switchport mode trunk.
How can I get the interface to work with the proper IP range for vlan 1001?

I finally had a chance to fiddle around with this issue again and have some more information on the problem. It appears to not be an issue with the IP address, but rather with the VLAN. The 172.17.0.0/16 subnet is on VLAN 1001 which it appears the WLC does not care for. This problem is repeatable on the following versions of code that I have tried:
7.0.220.0
7.1.91.0
7.4.110.0 (Not in use for production until we upgrade from WCS to Prime.)
Any thoughts? Moving the 1001 VLAN to another number would be a HUGE undertaking so if there is not an answer within the firmware on the WLC, I will have to bridge two VLANs with bpdufilter enabled... Not my first choice for sure...

Site gives message Server not found; ;Firefox can't find the server at (site name). Address is correct, network is connected. Don't have problems with most sites. Others can access this particular site easily.

Can't open any of the National Parks Service Civil War Soldiers and Sailors Systems sites. Get the message Server not found although others are able to open it easily. Network connection is good and addresses are good.

Desktops get "Server Not Found" errors with WRT160N

I'm sharing my WRT160N with 2 laptops and 3 desktops. My laptops connect to the internet ok... drops now and then tho... but my desktops frequently get a "Server Not Found" error. After repeated "try again" clicks, it eventually connects again. Any ideas??

Try this ;
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
Under the Setup Tab...reduce the MTU value to 1300 and save settings.
Also reduce the card speed of the dekstop... (assuming it is window XP)..Click on the Start button >>> Control Panel >> Network Connections >> Right click on the ""Local Area Connection"" icon and select properties-Here click on the "Configure" button- Click on the "Advanced" tab- In the "Property" box highlight Link speed and duplex/Connection type/Network or Media type- And in the "Value" box select 10 Mbps half duplex/ 10 base T/10 base half mode and click on OK.. Now restart the computer.

I keep getting the following error "server not found.....firefox can't find the server at http." when I try to log on to one certain website.

I was able to access this website prior to 2 weeks ago. I can access this website on other computers without issues, and I can also access all other websites on this computer.
The following is what is listed in the navigation bar when I get the error message.
http://iphantom.com/wisd/restricted.html?fn=Default&FP=l&ip=10.201.5157&ibip=66.206.97.9&ldu=l&re=0&bu=wps.prenhall.com
I noticed it says wisd/restricted, but I can log on to this website using my wisd computer without issue, and I get the same error message at my home/other locations. So I know that it is not restricted. I have used all the other suggestions "no proxy", shut down firewalls, but nothing has worked.
Any help with this matter will be greatly appreciated.
Thank you,

No internet, "PPPoE Server Not Found" message. Same problem with both old and new modems.

Help please!
My internet connection with my old Westell 6100 modem was working fine, then quit all of the sudden and would not restart. The DSL and Data lights on the Westell modem were both green. The Internet light alternated between red and off.
I tried every troubleshooting thing I could think of:
Powering down and re-starting the modem and computer.
Resetting the modem.
Checking all of the wire and jack connections.
I plugged my computer ethernet cable straight into the modem, bypassing my router.
I tried both Windows and Mac computers.
I plugged the modem directly into the network interface on the outside of my house to bypass all of my house wiring.
I checked all my phone jacks with a telephone tester to make sure both phone lines were working and not reverse-wired.
I made sure I did not have a DSL filter installed on the modem line.
Verizon Tech Support did a line test and told me the line was fine but that there might be a problem with either my modem or something at the "central office" (not sure what that means). Verizon also sent me a new router as well -- a D-Link DSL-2750B.
The new D-Link router also does not connect to the internet (same problem). The DSL, Data, and Internet lights are all green on the D-Link. I have the computer directly connected to the modem with a new ethernet cable. I repeated the above troubleshooting steps. I went into the router configuration 192.168.1.1 and ran the modem's "Internet Troubleshooting" tests.
There were two error messages on the router configuration screens:
1."PPPoE Server not found" error message is shown on the summary screen.
2."No internet infrastructure present. Please call your infrastructure provider." is shown in the "internet troubleshooting" test results.
Verizon had me change some settings inside the router configuration -- no dice. Verizon ran another line test. A "Level 2 Tech" took over the call and told me that he thinks that the cause of the problem is that the outside wiring coming to my house is reverse-wired. How can this be true since my DSL worked for 2 years before this, my phone line tester indicates my phone lines are wired the right way, and my router reports "PPPoE Server Not Found?"
Verizon is sending out a repair tech to check the outside wiring but I don't think that is the problem at all.
HELP!
Solved!
Go to Solution.

If you're getting DSL sync (solid DSL light), this sounds like a case of a bad line card to me. I've seen it happen before where it wasn't an account or route issue to the network.

Firefox has always opened with an extra tab that says "server not found." How can I fix this?

Several years ago, I downloaded Firefox for the first time on my Xp machine. The browser opens to the home page, but up in the tab area, there is always, and I mean through EVERY version and upgrade since that first one, including the most recent version 4, there is a second tab just to the right of the home page tab that says, "server not found." Now, since the home page loaded, it is obvious to me that the server WAS indeed "found." what I don't understand is why this second tab is there. Any ideas? I have read through the FAQ about not finding the server, and nothing there is relevant to this, as far as I can see.

How many pages do you have set as your "homepage"? 
Firefox allows for multiple homepages in separate tabs, separated by the pipe | symbol.
Try resetting your homepage.

Firefox opens websites when hard wired to router, but when using wireless I get a server not found message.

Firefox (3.6.10) opens websites when hard wired to router, but when using wireless I get message: SERVER NOT FOUND FIREFOX CAN'T FIND THE SERVER AT SEARCH.AVG.COM. My homepage is http://www.google.com/firefox?client=firefox-a&rls=org.mozilla:en-US:official. My anti-virus is AVG free 8.5.448. What can cause this?
If Work Offline is checked in Firefox File, I can get to Google search site. When I un-check it I still get the Server Not Found message

Did you check the connection settings?

+You may have already done this, but do you have the first AirPort Express configured to "Allow this network to be extended"?+
Could not find that setting anywhere.
It's in AirPort Utility, AirPort panel, Wireless tab.
When I'm within the range of the base station I connect normally, but further away the connection drops despite the fact that the other Airport is very close and light is green. Interestingly, my PB Pro has signal almost everywhere in the house, but my iPhone and Mac Mini don't. Most likely just a hardware difference?
In AirPort Utility with the second Express, in the AirPort panel, Wireless tab, have you checked "Allow wireless clients"?
The second AP does show an IP address: 10.0.1.3.
With a "Configure IPv4" setting of "Using DHCP", that suggests that the second Express really is connecting to the first Express. In that case I have no other explanation of your your problem.

Firefox does not load pages, comes back with server not found

First I thought this was a problem with Firefox 4 beta but now I am having the same issue with 3.6.16
About 70% of the times, Firefox does not open the web page and comes back with "Server not found" message. Interesting thing is it comes back with this message on the first 2 tries and then on the third try for the same link it will display the page. Always, 2 fails and 3rd time it works. Now during the first two times, internet commnection is working and if I try the same URL on IE it works without any issues. This started happening after I tried Firefox 4 beta. 4 is not uninstalled and I am back to 3.6.16. But the issue remains.
I am using Win 7 64 Home Premium, SP1 is not applied yet but all updates are in place.

Well, I'm using Firefox 4.0 and have the same problem. I tried to open my private homepage and my *.net-domain comes back with the "Server not found" message (my *.com-domain loads without any problem - same contents on both websites)
I also tried to open my net-domain in FF portable - without any problems.
Clearing the cache, deleting the cookies etc in FF4 does not help either.
I also had the experience that FF4 does not load CSS5 websites (e.g. deviantart) properly (CSS does not work, website shows simply the html-version, a disgusting look). With FF portable the problem does not exist.
I tried this on different machines (e.g. Windows XP Pro SP3 (office PC), Win7 Pro 64, Win Vista SP2... (home PCs) and there I'm experiencing the same issues with FF4 and various websites.

I can open any initial website but nothing within the website, says server not found

For the last few days, I can get to almost any initial website or bookmark but I cannot click open anything in that website without refreshing 4-10 times. I think it has been since I upgraded to latest version of Firefox.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:
*https://support.mozilla.org/kb/Server+not+found
*https://support.mozilla.org/kb/Firewalls
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.
