Using WinXP and IE 6, new T1 service, using their DNS servers. The hardware tech that installed the new T1 line and router was able to browse with his laptop. Tried my laptop with the same settings and cable, could not browse, PING worked with IP but not by name.

I did an ipconfig /flushdns and then was able to ping by name and IP. Called their tech support and they verified all IP, Gateway, DNS, etc. Still can't browse. I've also cleared all history and temp Internet files.

Anyone know where to go now?

TIA,
Don

if you can ping you've got connectivity. if you can't browse, you may not have permissions to do so or a firewall installed on the computer you are using to access another is blocking that.

Should have mentioned that within IE, no proxy is setup. The NIC is connected directly to the router with a x-over cable. No firewall either.

should have mentioned no proxy is setup BUT your laptop is connected directly to the router and no firewall...

First off you don't need a proxy setup in IE unless your on a network that has a proxy server for internet access which from your comment [see above] you aren't doing.

Second is, what your really trying to do is remote administration of the DNS server from your laptop. For that, you need to connect to the server via terminal services remote administration mode. THEN you can browse the server.

Next is, if your trying to "browse" ?????? [I'll assume the internet as I've discussed browsing the DNS server], and you can't, and your directly connected to the router, how does the router handle IP & DNS addressing???? If you want internet access via connecting directly to the router, how is IE configured? [hint if you have a static IP addressing scheme and the routher has DHCP enabled ooops isnt going to work]. If the routher is the gateway, do you have the router's IP address set in your NIC as the default gateway Address????

and final comment, IT people here approach questions such as these in the context of corporate networks with servers, workstations, and the lot. Only after asking a bunch of questions and getting a bunch of rejections and further information from the poster do we find out that this isn't about corporate networks but a home user having problems with their home DSL /cable connection & setup and cant' understand the Internet Service Providers tech support people [which I can't blame them cuz it's usually farmed out to a place in India or Siberia or a company that has switched from telemarking to customer service for ISP's. All of which probably read a piece of paper or someting they had to memorize during customer service training to troubleshoot].

If the later is the case, your a home user having troubles with your DSL/Cable connection, then give us the particulars of how Internet Explorer is configured, which make/model router and how its configured and which DSL/Cable provider you use.

last comment... again if you can ping, you have connectivity. If you can't browse the internet and get an error page showing in you browser such and Internet Explorer or Netscape stating DNS error, the browser isn't configured properly. If your browser is IE with IE open, click tools from the task bar, choose internet options, click on the connections tab, choose LAN settings. In the LAN settings properties page, if there are any boxes checked, uncheck them.

NOW, on to the NIC. From the control panel, open up network and internet connections, network connection. You should have an icon local area connection 1 . right click and choose properties. In the LAN connection properties box, click on TCP/IP [that will highlight it]and click on the properties radio button. This is where you would specify an IP address, default gateway addresses and DNS server addresses if your using a static IP scheme or if not and are obtaining one automatically from the router, check the box obtain an IP address automatically and check the box [if it isn't] obtain DNS server address automatically. You DONT imput the information for IP and DNS addresses in Internet Explorer. It's for the Network Interface Card NIC, and that is done from the control panel. IE You don't access the NIC properties page from IE but from the control panel. Many home users AND the damn tech support people make this mistake.

last comment on this.....[didn't read the fine print !!! ] why are you using a cross over cable to connect directly from your laptop to your router? Cross over is usually for just connecting 2 computers together in a loosely coupled workgroup. Run out and get a Cat 5 Ethernet cable and plug it in. You'll most likely be able to " browse"

I am using my laptop at work directly connected to the T! router until I get this working. Then I will be using Proxy and firewall. I am using a Xover cable for the same reason you use a xover when going computer to computer, because you must. If I can ping any site in the world by name or IP; how would switching to a straight through cable work? (It doesn't) I've already stated that tech support checked my IP, gateway, etc. NIC and IE settings.
Thanks,
Don

1. You may have Winsock2 setting problem and may need LSP-Fix (http://tinyurl.com/fg7q) to resolve it.

The following quote from the above site explains a ton.

?Repairs Winsock 2 settings, caused by buggy or improperly-removed Internet software, that result in loss of Internet access. LSP-Fix is a free utility to repair a specific type of problem associated with certain Internet software. This type of software is known as a Layered Service Provider or LSP, a piece of software that can be inserted into the Windows TCP/IP handler like a link in a chain. However, due to bugs in the LSP software or deletion of the software, this chain can get broken, rendering the user unable to access the Internet.?

I have not used this software but after searching websites, this is well worthy trying.

Remove all virus/worm/Trojan/spyware/adware and backup your data before trying the followings.

2. Reinstall Windows on top of it.

3. Clean install Windows as a last resort.

If you are not running a firewall, try going to http://www.grc.com and getting that site to check your router for security. May give you some clues, but if it is a router/firewall, you will have no joy, as it will stop everything at the firewall on the router.

You mention that you can ping, but what can you ping? The router? Your ISP? Any old URL? Someone else on the Internet? If you can ping your ISP but not browse, it could be a routing problem in their area. If you can ping your router but not the ISP, then it may well be a gateway problem your end.

just a thought - have you tried a tracert to a url? That can sometimes give you a clue, if your ISP will allow it (mine doesn't!)

I had considered running Shields UP from grc.com, but it automatically gets your IP address. I can't browse to it and if I go there from a different computer, I can't enter the IP that I want tested.
I can PING any site anywhere by IP or name. Because PING works, so does Tracert, goes all of the way to Yahoo.com for example. I believe that the problem is in IE or winsock, I just can't figure out how to fix it.

Thanks,

Not using DHCP, as mentioned, IP, Gateway, etc. have been verified. Can ping, so it can't be connectivity.

Thanks,
