Okay, I've got to explain this in a way that translates that shear nonsense that happens here.  So I search web part taht search oracle for client ids, brings back the client id and sends it to a redirect page.  The redirect page has a web part on it that grabs the client id from the query string and either creates a page for the client if none exists and then ships them to the page, or just sends them to the sharepoint page.  On the client's page, There's quite a bit of custom functionality through the use of javascript and custom web parts...  The client page is also given a query string "NC_NUMBER=346" to tell the page which client it is so the custom webparts can query oracle for some related info about the client. So thats the scenario.  And this works perfectly on my computer and a couple other peoples computers, however, when certain end users try to get the client's page, they get a:

"List does not exist

The page you selected contains a list that does not exist. It may have been deleted by another user. "

 Now, this is nuts enough just if it happened when going through the redirect page, however, it does this if you attempt to open a new IE window and paste the url with the nc_number parameter.  No redirect involved...  AND THEN, check this out, if you go to the site, get the error message, and then hit go back to page, it will load the page no worries.

 What seems to occur on the users page, is the sharepoint pulls some query parameters out of no where, one is "Type=List", the other is "name=%7B8B280387%2DF33F%2D4F4F%2D811C%2DF6A4FF8949B6%7D."  And of course no list with this guid exists on this site, thus the access denied error message.  Now why sharepoint appends these query parameters to the url is a mystery to me. 

 CAN ANYONE SHED LIGHT ON THIS???  Thanks in advance.
