Users Data not available on their "H" drive after they save the file. File server Windows 2003 and client Windows 7


We had windows 2008 DC and XP in the past and an IT company migrated the DCs from Windows 2008 to Windows 2012. Our file server is running on Window 2003
Recently I migrated all the 150 workstations from Windows XP to Windows 7.

Since the migration we have Problems with students losing their course work.
1) The students do the course work on a word document on Computer-A, spending 2-4 hrs and they save to their “H”, which is their home drive and gets mapped, when the students login.

2) Next day they log into a Computer-B and not able to locate the document they saved previous day. But when they go and log into the Computer-A (Previous day that was used), they can see the document there.
This is really causing a serious problem; student’s spent lot of time doing the course work and file missing.

Also on another occasion I came with a sort of similar problem i.e., there a word template in the students home drive and it contains 15 pages and the students have to fill in all the pages with thousands of words.
Many students have reported saying that they filled 10 pages spending many hours and saved it to the same H drive. When the login into different PC the same day \next day they are not able to see any data that was filled.

The data that was filled all the 10 pages are blank. When they go to the PC they logged in previous day they can see the Data in all the 10 pages available there.

Please guys help, not sure what is happening, and this is happening randomly with users.
Any help and would be really great.

I tried it a couple of times; the first time it wouldn't open, the second time it did.  Here's the relevant text from the KB article to do the fix manually:

To resolve this problem, re-initialize the cache of offline files. To do this, follow these steps:

1.  Click Start, type regedit in the Start Search box, and then press Enter.
          Note: If you are prompted for an administrator password or for confirmation, type the password or click Continue.
2.  Locate the following registry subkey, and then right-click it:
3.  Point to New, and then click Key.
4.  Type Parameters in the box.
5.  Right-click Parameters, point to New, and then click DWORD (32-bit)Value.
6.  Type FormatDatabase, and then press Enter.
7.  Right-click FormatDatabase, and then click Modify.
8.  In the Value data box, type 1, and then click OK.
9.  Exit Registry Editor, and then restart the computer.
        Note:  Make sure that files are synchronized before you add this registry entry. Otherwise, unsynchronized changes will be lost.

You can also automate the process of setting this registry value by using the Reg.exe command line tool. To do this, run the following command from an administrative command prompt:

REG ADD "HKLM\System\CurrentControlSet\Services\CSC\Parameters" /v FormatDatabase /t REG_DWORD /d 1 /f

•  Make sure that files are synchronized before you add this registry entry. Otherwise, unsynchronized changes will be lost.
•  The actual value of the new registry key is ignored.

This registry change requires a restart. When the computer is restarting, the shell will re-initialize the CSC cache, and then delete the registry key if the registry entry exists.

The most logical answer to this problem is that the drive mapping/redirection of their home drive isn't working properly.  Assuming that the student logs in to every computer with the same user ID/password, they should see the same home drive.  You need to do some troubleshooting by experimenting with a user ID that is having the problem, logging on to different computers, making a small change to the home drive contents, logging off and then checking the server shared resource that stores their home drive folders.  This is the only way to determine how and where the problem exists.  When you find a situation where the contents weren't saved properly, you need to check the event log on the workstation in question, and you'll likely find folder redirection and/or write access errors indicating a failure to connect to that resource. From there you should get an indication of what is happening.

Please post back with the results of your testing.

Sorry , it took a while to do some investigations, please see the attached Snapshot's and the two different scenarios that I had observer and the event logs on the problem PC. please let me know if you need any further info.

Thanks so much.

Ok - I see a problem here in that you have both Documents folder redirection and folder synchronization turned on on both of these PCs.  The ONLY time that you should have folder synchronization turned on is if the user routinely disconnects the PC from the network and needs to work on documents offline. For example, if the user has a laptop and works on it in the office and then takes it home and wants to have an offline copy of his/her documents to work at home.

As a general rule, if you're using Documents redirection on the home folder, you should turn off folder synchronization, unless the above situation exists.  Folder synchronization can be problematical, especially if a user logs on to different PCs on the same network.  The PCs will try to synchronize the folder at each location and it can lead to corruption of the sychronized copy, which is what you're seeing on PC2.

Thank you so much for identifying the fault.

We have only few students who take their Laptop to home . I will set up a remote file access for them using HAP+

Please post me some tutorials to turn of the folder synchronization in the GPO. After if turn off the folder synchronization  I will replicate the same on the same PCs will post the results.

To prevent the synchronization of redirected folders in group policy:

User Configuration/Policies/Administrative Templates/System/Folder Redirection/Do not automatically make all redirected folders available offline

Edit this settings and set it to Enabled.  This will turn off synchronization for all redirected folders.

On PCs where folder synchronization has been enabled and the synch folder is corrupted, you may have to clean that up:
