gmail is blocked in my office i just want to check my mails in gmail is there is any other way to access gmail

I tried Ronnie's (March 13, 2005) solution of editing the Registry and creating a DWORD of MTU and giving it a value of 1492 - and as soon as I rebooted, I was able to get to all the sites I couldn't before. I had 7 or 8 subkeys in the Interfaces directory and wasn't sure which one to change, so I just changed them all.

Now I wonder if there's any harm in creating all those DWORD values with an MTU value of 1492.

... and what does this actually fix?

Ronnie is our new hero, we have been trying to get the laptop to access ebay for weeks now and tried absolutely everything apart from throwing the damn thing through the window ( which was the next step).
Ronnies solution worked first time.
Hallelujah!!

Sound advice....
I had this problem and tried the above and it worked, i read futher into it and found out the following

As far as i can gather changing the DWORD is something to do with the modem or file and printer sharing. Some modems as soon as they install automatically set a dword value for the ONE machine but when you add more and more machines the modem value which was set is not good enough so it needs to be changed. You will always be able to access sites on the main computer but on network computers the dword needs to be changed.

If you have lots of values, remember its the one with the i.p address included!

I've tried the regedit solution with no success...any other ideas?

Can anyone explain why one user account on my XP (SP2) machine can access the Ebay login page while another can't? I'm going to try the MTU solution tonight but I'm not holding out much hope because that's a machine-wide setting, not user specific.

Also, when I created a new account to replace the one that can't access Ebay, it worked for a week or so but now suffers in the same way. My own account remains unaffected.

As an experiment I used the various different options of the "files and settings transfer wizard" to move some setting over to a set of temporary accounts. Without fail each account worked before the transfer and failed afterwards. My conclusion from that is that it's definitely a registry setting that causing the problem.

The machine is on a small home LAN, connected to the net through a 3COM ADSL router. I can't see that this has any bearing though, because it's only that one user account on one machine that has the problem.

Anyone got any further info??

Hi, i tried the above and it worked fine, i can now access the ebay home page again,

Thankyou i new i would find the answer on someone message board.

I came across this forum the other day and read the comments with great interest because I have suffered the same problems noted by everyone here; not being able to access some websites (e.g. BBC news online) and not being able to send or receive email.

My setup is: One PC running Windows 98 connected to the Internet (via dialup). Two PCs with XP Professional, one PC with XP Home, all the machines linked together on a wireless network.

Everything was running fine and dandy until early April this year when the email went down and some websites were blocked. The problem was confined to the XP machines but not the Win 98 PC.

To cut a long story short, I've managed to cure the problem. My solution was to remove Windows Hotfix KB893066 and I was able to access my email and the "blocked" websites straight away. I discovered this by accident. I thought that the problem might be related to SP2 and when I removed it from one of my PCs, everything worked fine. Despite the fact it seemed very drastic, I was going to remove SP2 from the other XP machines but I noticed that Windows updater was working away and eventually it wanted to install something... KB893066. As soon as I installed it, everything went down again.

I'm not suggesting that my solution is the magic bullet for everyone with the same problems but it worked for me. The Knowledge Base article on this hotfix talks about "network degradation" and the fact that connectivity between clients and servers may fail.

One thing is sure after this episode: I'm going to turn off automatic updates on all my PCs. I'd stupidly left it on thinking that I could trust MS to deliver updates that didn't cause problems... doh!

Why am not able to see this site webisolutions.com using my broadband connection but I am able see it on other connections.
