Corruption of URL causing 500 error

 

I am not sure if any one else is getting this. I have a feeling it is IIS or the web server that is causing this, but I am getting errors on some of the URLS that users can click on. So when the user clicks on this, it is causing a 500 error on the server. I must point out that I have not seen this myself. I do get emails from ever 500 error that the server generates, so I get notified when these errors occur.

 

Yesterday the google bot caused 30 of these errors.

 

This is the error information that I got :

 

I checked the version that I am running on the server and it is 8.04. I then downloaded all the files to make sure that there were no corruptions, and they are the same as in the release zip file. The only files that are not the same are the layout files, css, and header etc.

 

Unfortunately it is not just isolated to googlebot, as I have had some errors from users on the activate.asp page. Just to add some additional problems, the errors have occurred to IE and firefox users. The only thing that they have in common is the corrupted data at the back of the URL. I have tried to get a copy of the email, but to date I have not managed to get one. This is a rather tricky and annoying little problem, as I have not had this happen to me it is rather difficult to track it down. If you have any ideas of any way of finding what may be causing this, I would greatly appreciate it.

 

Thanks
