error message accessing various websites

Scott,

Are you behind a proxy server? We have had issues before where because we are behind a proxy server, the web server looses the temporary connection to workstation through the proxy, and by clicking back and then submit again you are re-establishing the connection to the server and your submitted information goes through.
You may want to verify that none of the settings have changed in your browser and that your admin hasn't changed anything on the Network/ISP side.

Hope this helps.
Thanks.
Mike

Cause uncertain, but this was observed on a web site that used a LOT of cookies. When the message occurred, about 1776 bytes of cookies had been transmitted. Perhaps that is too big for the storage available to receive them.

Scott,

What operating system are you using? Are you receiving any information in your event logs? What version of Internet Explorer are you using? What service packs or patches have you applied to your system?

While I have never seen this message before and I am not sure which OS you are using, I did find a server related issue on Microsoft's website. I don't know if you have seen it, but Microsoft KB 249721 refers to the same error message. This article applies to servers running IIS 4.0 accessing asp pages. The article recommends running the latest service pack on the machine to correct the issue.

While your issue is probably not on a server running IIS 4.0, have you tried to update IE or get the latest service pack? I know that the blaster worm patch has fixed quite a few problems around the office (even the ones that are completely unrelated to the worm).

The problem may also be related to active X issues. Have you changed any security settings lately?

I hope this helps bring you closer to solving your problem.

Sincerely,
Marco
