Browsers can't find server (Internet) randomly

On iMac with Snow Leopard OS, Firefox randomly and for very short duration would tell me I was not connected to the Internet...except that I was and could access it seconds later. Uninstalled Firefox and tried using just Safari. Same problem, random error messages saying I am not connected to Internet when I clearly am. I can access the website I'm trying to get to by going a different route or I can access another website. We have a Windows 7 laptop with Firefox and an iPad using Safari and neither one has this problem so it isn't the wireless router. What else should I be looking at? Thanks!

I thought it worked at first, although I never found the CaptiveNetworkSupport folder. I deleted com.apple.airport.preferences.plist and the other two you listed. Restarted and then had to "find" the router again. No problem for a couple of days but tonight it's told me twice it can't find the server. I'd say it was an old modem/router (2Wire) but other devices on the network don't have this problem. Thanks for your suggestions Zane. Wish it had worked.

Connected to the internet but browser says 'can't find server'

Hi,
I have an Apple Airport Extreme and it has been working well for a long time. My husband and I both run our internet connections from it wirelessly. Recently, when we go to connect to the internet, the browser says 'Can't find Server' but the Airport status bar says we are fully connected to the internet with a strong signal. I have no idea what happened or what is going on. The only thing that we have done differently is update the firmware on both our computers, and it seems as if this problem has started around that time. Any suggestions would be greatly appreciated. Thanks

It might be a good time to perform a complete power recycle of your network components to make sure they are "talking" to each other properly and see if this resolves the problem.
Please try the following:
o Power-down the modem, AirPort Extreme Base Station (AEBS), and computer(s); wait at least 15 minutes. Order is not critical.
o Power-on the modem; wait at least 10-15 minutes.
o Plug-in the AEBS; wait at least 5-10 minutes.
o Power-on the computer(s).
Can they access the Internet now?

Connected to internet, but can't find server.

I have an 8gb 1.1.4 software. I have a wireless router in my house and I entered the password correctly, it says I am connect in the corner but when I go to Safari it says can not find server.

Exact same issue as my daughter had with her 1G Touch. Tried all suggestions found in this forum since mid-summer, and no luck. She sent it in to Apple for a replacement, and same thing with the new one. She has DSL with a modem/router from her provider and a Linksys wireless G, and her HP laptop connects wirelessly with no problems. We spent an afternoon trying different modem/router and Linksys settings and no help. I finally called her provider and complained that not only was the iPod touch unable to connect, but neither could the PS3, Wii, or Nintendo DS. They immediately OK'd a switch out of her Westell DSL modem/router with a new Zone. Everything now connects with no problems.
This is probably not your solution, but, boy, it sure worked for her.

How do I get help when no updated browser can load a particular site,"can't find server,"

In recent weeks, possibly coinciding with updates in Firefox (running 3.6.10), Safari and iTunes, I have only received the prompt, "can't find server" when attempting to connect to the site below. Others can get it on their computers in other places, and my iPhone can access when on 3G, but our network here seems affected because all the computers [All macs, some laptops and some desktops, running on OS 10.5.8] here receive this message. I used to be able to go to this site, a radio station, and stream audio or download podcasts. My ISP ran a ping test to the site's server and said that went through, but the browsers don't seem to be able to make the transformation to anything I can read. What kind of a problem is this? Apple was no help either.

Well, it's very interesting that without my doing anything else, last Friday, kcrw.com mysteriously APPEARED when I went to it. This happened in Safari, too. It loads and I can stream the audio (with the Flash update). No explanation, really.
I had checked the protocols, but everything was default. It took all week for the change; so I can't believe that my tinkering (which was really only checking and doing nothing) was the cause of the reappearance.

WebtopNaming - can not find server name for server ID

We have a LB, and web servers in front of OpenSSO app servers in our environment.
OpenSSO debug log CoreSystem fills up with lot of errors like these:
ERROR: WebtopNaming.getServerFromID() can not find server name for server ID : 07
com.iplanet.services.naming.ServerEntryNotFoundException: Cannot find server.
Sometimes, it even complains about a server id (07 in the following trace) which doesn't even exist in the Site Id Table.
There are no changes in the configuration. DNS is properly configured and all the servers and their connectivity are available. CoreSystem throws these errors even after a restart of opensso app servers.
Any ideas about the root cause?

Thank You for the response.
Here is my site configuration in OpenSSO:
There are 4 servers in the two opensso hosts (2 secure, 2 non secure)
Servers:
http://host4.company.com:8080/openSSO
http://host5.company.com:8080/openSSO
https://host4.company.com:8443/openSSO
https://host5.company.com:8443/openSSO
Only one site with secure URLs is configured
Sites:
site1
Primary URL: https://opensso-qa.company.com:443/openSSO
Assigned Servers:
https://host4.company.com:8443/openSSO
https://host5.company.com:8443/openSSO
From the CoreSystem log, Server ID definitions are:
https://host4.company.com:8443/openSSO=01
https://host5.company.com:8443/openSSO=02
https://opensso-qa.company.com:443/openSSO=03
http://host4.company.com:8080/openSSO=04
http://host5.company.com:8080/openSSO=05
Sometimes it throws an exception with existing server IDs. But sometimes it also complains about non existing server IDs.

It sounds like you've got a messed-up homepage. Click the Safari menu, click Preferences, and under "Home page", re-type the page you'd prefer to load when Safari starts (eg "nytimes.com" or whatever). Close preferences and try again.

Can't Find Server at... error -- only one site, works from non-Macs fine

Greetings:
I have been getting a "Can't Find Server at www.teocommunications.com" error in Firefox for over a month now. I thought initially that it was a problem with the DNS entries and maybe the record had not proliferated though the DNS servers of my ISP or something of that nature. This is not the case.
I have tried to bring my site up in Safari and it yields the same result.
Did an nslookup, and everything resolves fine. Every once in awhile the site comes up on my Mac, but most of the time it gives the error. At all times, if you try to go to it from a Windows machine or my smart phone it works fine 100% if the time. My wife's Windows Vista machine with Firefox brings it up fine 100% of the time (she is on the very same network). I can get it to work for some reason if I totally reboot the Mac or reset the router (but the router is obviously not the problem)... it has to be something in the Mac OS (10.6 and 10.5) that is going on. I have eliminated all other possible problems. Curiously enough, it seems to also be a Leopard (not just Snow Leopard) issue... I can reproduce the error at my school (which is on a totally different network than my home) on the Mac Pro Intels they have which are still on Leopard.
I am on the latest version of Snow Leopard on a brand new Mac Mini.
This problem is only with my site (that I know of) but again it happens ONLY on Macs with Leopard or Snow Leopard. I am very annoyed by this problem and because it is my professional work site, it is imperative that I find the solution and soon.
Hope someone can help.
APPLE, please look into possible configuration or DNS issues in Leopard/Snow Leopard, as before I posted here, I did try several 'fixes' for issues like this for Firefox before I noticed that Safari was getting the same issue and ANY OTHER PLATFORM sees my page just fine!

Hi Guys:
It sometimes works from my Mac as well. I can get it to load if I reboot the Mac and then in a few reloads it is back to the same error.
I did try openDNS as well and it did not still load. I can pretty much guarantee that it is not the DNS records, it is something going on between my Mac (or the Pros at school). Other sites from my same host work fine, my domain is setup exactly the same. They do use ISPConfig... and it could be something with that program, but I can not seem to confirm any problems there.
I reset my router and the site is currently loading again on my Mac, but I can tell you it will be throwing the error in the very near future because that is one fix that worked before and it worked exactly two loads when I switched to a different wireless access point that is not my router.
SO, the fact that it loads one to up to twenty times on someone's Mac is not enough to reproduce the problem. It takes several reloads and then the problem magically re-appears. This is why the fact that it is working right now on my machine is not good enough to call it fixed.
Try to reload my site several times and see if it gives you the error.
I have (as I stated) tried a lot of what is being suggested here and re-tried it, but nothing fixes it for very long
I appreciate the help and hopefully we can figure out why the situation exists.
Thanks for the help so far and please feel free to keep suggesting ideas, but for reference I have tried:
1. modifying settings in Firefox (although it does not matter what browser I use,the result is always the same)
2. resetting the router and DSL modem
3. modifying the /etc/hosts file on my Mac
4. dscacheutil -flushcache
5. using openDNS instead of my ISP (which is AT&T)
6. removing the DNS settings and using the router settings
7. turning off airport and back on after 30 seconds
8. renewing my DHCP clients
9. Signning onto a different wireless access point (which is actually a new ISP that I am going with and so they are a totally different network and subnet).. they are setup all over town with wireless access. -- pretty cool actually.
None of this seems to fix the problem loading only my site. Since I do have access to the hosting provider (I work with them)... I have done some things on the hosting side too. All to no avail.

ICal reports that it can't find server, and lots of data from several years ago is trying to get attention. Cannot bring up calendar in any view to use. also keeps loading unused calendar websites from long ago. I can' remove them. what to do?

UPDATE: I had 36 Safari windows open and minimized on the dock from my last session; 20 of those windows failed to open b/c Safari "couldn't find the server"; I just went to the URL bar of all 20 pages and clicked return, and all 20 pages loaded perfectly, without dropping any images or losing formatting. This is a puzzle!!!

Get error "Safari can't find the Internet plug-in"

I get error when I tried to open a Potcast on IBM's website in Safari 5 for Windows 7
"Safari can't find the Internet plug in. Some content on the page "IBM Cloud Computing - idea - United States - United States' Can't be shown because its MIME type is unspecified.
I checked these settings
-Plug-ins enabled in edit\preferences\security
-Java enabled in edit\preferences\security
-JavaScript enabled in edit\preferences\security
-Quick Time Player 7.6.6 is installed and works
-Potcast works on Google and IE. Note: IE prompted for MIME type configuration, clicked Yes and Potcast worked.
I tried to search the web for answer but couldn't find solution for this error.
I checked Apple's forum and didn't find anything so Please help.
thanks

Is that the "Listen and learn about cloud computing and the IBM difference" podcast on this page, Concise?
http://www.ibm.com/smarterplanet/us/en/cloud_computing/ideas/index.html
If so, I can replicate the effect on my XP SP3 box (running Safari 5.0).
A bit odd, because it just looks to be a QuickTime plugin when I click on it in IE.
The W3C Markup validation service doesn't like the code on that page much:
[88 Errors, 69 warning(s)|http://validator.w3.org/check?uri=http%3A%2F%2Fwww.ibm.com%2Fsmarter planet%2Fus%2Fen%2Fcloud_computing%2Fideas%2Findex.html&charset=%28detect+automa tically%29&doctype=Inline&group=0]
... but it might be worth doing a "Help > report bugs to Apple" (in Safari) just in case the effect isn't related to the code.
(If anyone has suggestions for Concise on workarounds to get safari to play the podcast, please feel free to leap in.)

Error message, "safari can't find server"

I installed the latest version of Flash Player and ever since then I have had several error messages - "safari can't find server". I tried uninstalling, then installing it directly from the website the next day, I also emptied cache and reset safari. No luck - any suggestions? Thanks in advance!

Ok. Let's now create you a new location and see if that fixes it:
System Preferences > Network
In the Location section at the top of the window, click on the combo box and select Edit Locations...
Click on the plus sign and give your location a name (like Home), then Done
Now select Airport from the side bar, make sure Airport is turned On.
Set the correct network name
Now click on Advanced
Select the TCP/IP tab, Configure IPv4 as [Using DHCP], now click on Renew DHCP Lease and wait
After a few seconds you should get an IP address of 192.168.xx.xx and the Router field filled in.
Now go to the Proxies tab and select Auto Proxy Discovery, and use Passive Mode
Click on OK, make sure Airport is still select, then Apply
Fingers crossed! This should now work...
Good luck
Bob

Safari quits all the time, can't find server, garbled texts

Safari can't find server, will not browse, quits all the time, garbled texts, don't know if I am using safari and snow leopard or safari with ox lion which i have upgraded recently.

SOMETHING ABOUT THE HARD DRIVE SYMBOL START UP?
I don't understand this.
I also disabled third party addons, is that wrong?
If you mean Safari extensions, that's OK. Extensions are not necessary in order to use Safari.

Firefox does not load web pages; it always says 'can't find server' on every page I try to load

Firefox 'can not find server' reply comes up on every page I try to load, including my home page. I have to retry or refresh 3-4 times before it takes.

Sounds like a proxy server issue. Go to System Preferences... > Network
Select the AirPort from the left hand side
Click on the Locations combo box and select "Automatic"
Click on Advanced
Select the AirPort tab and enter your network name
Select TCP/IP tab.
Configure IPv4 Using DHCP
Now click on Renew DHCP Lease. After a few seconds you should get an IP address (probably 192.168.x.x)
Click on Proxies tab.
Select Auto Proxy Discovery and Use Passive FTP - de-select all other options.
Click on OK and Apply, etc.

ITunes can't find firefox internet connection

The iTunes program downloads and installs fine,but when I go to connect w/iTunes it can't find server. I checked the connection in my computer and it is fine. I disabled the firewall and nothing. Explorer is also in my computer, but it is not my default server.

Does your modem have a battery? - if it does then you have to unplug the modem, pull and replace the battery and plug it back in - wait until it completly boots and then power-up the Express - if this doesn't work, what is the light on the Express doing? - and you should be able to check the Express by plugging the laptop into the ethernet port and opening the AU - it will tell you what errors are showing.
