I have a user that is an approver on a workflow. When this user gets a notification that he needs to approve a request he goes to a task list, clicks on the request, and then clicks approve. His browser is then redirected to a page that returns the generic IE "Page cannot be displayed" message.
Another user is (and I also am) an approver for this workflow as well. When we go through the same process, the workflow is approved as it should be. I've double checked and all of our rights for this site and workflow are identical.
Also at times, the user in question clicks on the task from the task list screen I mentioned earlier and his browser is directed to the generic "Page cannot be displayed" message.
Here is what the URL looks like when I go the the approval screen from the task list
Here is what his looks like:
What are some things I can look at to fix this?
