SharePoint 2010 - unable to download documents from any site

SharePoint 2010 running on 2008 Server in a vSphere 4.0 virtual server.

Issue: Unable to download doc, docx, ppt, pptx, etc, etc, from any site. Cannot open the documents, cannot right-click save as, cannot drop down menu and save as, cannot edit, cannot checkout, etc. Can upload documents fine - but as soon as try to download same document, above issue occurs.

There is no error. It attempts to open document, it attempts to download document and it gets 0%. I then have to cancel the attempt. It all happens very fast, getting 4ms ping rate to server.

It is not consistent. Sometimes it WILL allow you to download certain documents, with no rhyme or reason. I have looked for one.

I will not be able to test and come back and give results. I can just go do and then award points to the people who has best suggestions, regardless if it resolved the issue or not.

I am hoping someone has seen a similar issue and can point to web articles or give advice on tracking down the issue.

I know I have not provided enough setup information, but this is what I can give. Also, if anyone knows for sure, could this be related to DNS/DC in any way? I think it is network related, but I need to make sure I check all I can check.

My portal is having the issue. I am guessing no one has seen this issue.
Hi Dassey.  If you open the site in a browser on the server itself, does the same thing happen - or is it only when you access your site from a client PC?

I know you don't really want to try solutions, but I would recommend installing HTTP fiddler on a client PC ( and using it to inspect the traffic between the server and client.  The HTTP status codes and the content of the HTTP messages may reveal the problem.
