Users redirection not applying intermittently
We are experiencing a real weird issue around the entire site and from what we can see, it is totally intermittent.
Symptom of Issue
Students log onto workstations around the school, on different types of machines all with the same Windows 7 Enterprise image. The ideal logon would be to have a redirected start menu, desktop and documents which are all located on our file server.
Most of the time students logon with no issue but randomly we get some users who may not receive one of the three or possible none. We have been able to identify that the issue does not relate to a particular user, workstation etc. The reason that this is weird, is that the same user can move location to another PC in the room and the logon works. Other users may then go to the faulty machine and use it with no issues with redirection.
Event viewer logs show the redirection has access denied and yet permissions are set correctly as we set them via a group.
After some testing we have managed to replicate the issue by logging onto a machine as a student and then just as you get past the welcome message, pull out the network cable.
Upon doing the above, the test student will experience the issues stated. We have then tried restarting the PC on numerous times and yet the student still recieves no redirection of any kind even after removing the local profile.
Another interesting issue we have seen is that when the student recieves this problem, we have tried accessing the File Server and shares for desktop through explorer but recieve access denied!!
We are now at the end of our tether and staff/students are getting really frustrated as we have no fix for them when the issue occurs other thatn to move pc.
We are now thinking its image related??
Windows 7 Enterprise workstations using same sysprep image
Windows Server 2008 R2 Servers over Hyper V
Blades on 172 address range with VLANs
Workstations on 192 address range so not to affect CCTV and VOIP.
Core switch has Helper address for two networks
