After a recent batch of updates that included installing IE9 we have had a number of computers 20+ that have started exhibiting problems. Most of them have problems shutting down. It appears that on some it will only happen for one day where as on others it continues to happen. In addition we have had a few of the computers become very slow on the Internet when using IE9. A task that normally would take 4 to 5 seconds to load or run will take 2 to 3 minutes.
We have verified that Java was current, we used ccleaner to clean up one of the computers, but nothing has helped. We also were getting a missing dll message for mfplat.dll on some of the computers. We think the problem is related to the updates that were installed around 5/1/2012.
Anyone with suggestions or experiencing similar issues?
