We run a very old application that connects to an MS SQL server 2008 database using the SQL server native client 10. Sometimes if there has been a power failure with the server the clients will stop communicating with the server. Normally in the past we have just uninstalled the SQL server native client and re-installed it and that would get things working again. This time it is not working. It seems to be a problem with the specific user profile on the client machine (Win 7 Pro). If I recreate the account everything works fine. On some clients there are user profiles that had not been logged into for more than three months that did not seem to be affected at all.
When the application is opened these windows pop up after hitting OK and cancel a few times.http://imgur.com/a/qvb7d
