Recently our SharePoint 2007 system started giving the error "the Connection was reset by the server" when loading some pages. At first we thought it was just html documents uploaded by users, however I found a few of the .aspx pages that are doing the same thing. I checked the SharePoint and windows logs and have found nothing that points to the issue. After a great deal of troubleshooting I did find that all the documents that are having troubles being displayed have a VML namespace declared in the document. Generally it looks like this:
<html xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:w="urn:schemas-microsoft-com:office:word" xmlns:m="http://schemas.microsoft.com/office/2004/12/omml" xmlns="http://www.w3.org/TR/REC-html40">
I did some packet sniffing and as far as I can tell when the request fails the server starts to send the data then sends a TCP packet with the reset flag set to true.
Do any of you have an idea of where to look to find why the server is resetting the connections on these documents?
