Home drive failing to map on specific computer

[Gaz]

For some reason today a computer (Win7 Pro 64bit) has decided it wont map the home drive for any user that logs on, however it does map a drive thats mapped via a script and another that is mapped via "map network drive" in my computer
All other parts of the network appear to be working fine.

The Event log says:
Folder redirection policy application has been delayed until the next logon because the group policy logon optimization is in effect.
Also for My Docs redirect
Failed to apply policy and redirect folder "Music" to "\\LTC\Students\testacc\My Music".
Redirection options=0x9001.
The following error occurred: "Can not create folder "\\LTC\Students\testacc\My Music"".
Error details: "Access is denied.

Make sure you haver read access to that share.
Try connecting using a different account.

Does the computer have a memory card reader using up drive letters? Check in Computer Management.

Is it in the correct OU?

[Gaz]

Sorry for the late reply I just assumed no one had replied because I didn't get an email notification.

Only student accounts seem to be effected. Teacher accounts arent even though they are both limited accounts.
Yes its in the correct OU.
No other drive letters taking over the drive letter.
They have read access to the share.

This is a real noggin scratcher. I've tried everything I can think of but the student home drive still isn't mapping and its only this computer. :/
I've tried taking it out of the domain and adding it back in and still no joy.

OK I think this may be related. I've no idea how this has happened or even how its possible. If you look at the attached image you can see there are loads of "My Documents" folders but they are shared with the students username. This may be related to the problem. I think My Documents folder redirection has gone horribly wrong somewhere.

I tested with two accounts: student1 (a temp student account) and testacc (my student testing account) student1 wasn't renamed to "My Documents" but testacc was, however they were both still effected.

Is this only happening to the student on one machine, I ask because I had this issue with a Staff member once.

With the following symtoms

1. The staff member could logon to a different machine and got their home drive ok.
2. Anyone else logging onto the machine got their home drive including newly created test users.
3. Did not use roaming profiles, tried multiple profile removes on the local machine.
4. Tried recreating the users home area from scratch, recreated the users account as well I think.

In the end almost at last resort after a few hours mucking around I re-imaged the machine and all was ok again for that user??????

Hope this helps

It only seems to be student accounts that are effected and its only this machine. I just created another student account and it didn't map.
I also don't use roaming profiles so I may try deleting the local profile of my test accounts.
The symptoms are similar but I'd like to know the cause. If more computers were effected then I'd probably go the imaging route.
Imaging is a last resort.

[Davit2005]

The issue I had only was effecting one machine so it may be worth just re-imaging. If it a student machine it shouldn't take that much to get back up and running?

Alternatively swap out with another machine in a completely different area to see if their is some sort of networking/hardware issue, see if the problem moves with the machine.

This may or may not be related to DNS. I've just tried mapping it via an IP address.
net use /delete h:
net use h: \\192.168.10.1\students\%username% <---works
net use /delete h:
net use h: \\ltc.ltc.local\students\%username% <---works
net use /delete h:
net use h: \\ltc\students\%username% <---does not work

The DNS records look fine.

2008 R2 prefers FQDN paths?????

Do the redirects point to a 2008 R2?

Another route would be to scrap the net use for the h drive in the batch file and use the home path variable in profile tab on the users AD object. This could be tested with that one user by just pointing them to a different batch file. Copy the batch file, rename and REMout the home drive i.e: REM net use h: \\ltc\students\%username%

I would seriously consider re-imaging machine if it's only effecting one machine, you may not know what a user has done on that workstation which may of effected/corrupted a particular file???? As mentioned I only had an issue similar once in 14 months.

DNS, specifically suffixes when dealing with dfs can take a while to get sorted after boot on some stations, full paths or even additional A records for dfs can help. Why not just use the full dns path for everyone if it works?

You can also push dns suffixes through GPO however full paths are probably better.

Is sync centre turned off. May be worth clearing out offline files cache seen that cause similar problems when it gets it knickers in a twist

Sorry for the confusion, the drives are mapped via the home path variable in the profile tab. The net use stuff was while testing to see if the map still worked and the commands were executed using the test accounts.
I've just tried mapping it via the home profle using the FQDN and it works. Its just I've been using it the other way without any problems for years. Then suddenly a few weeks ago it starts acting up.

Where might I find sync centre? Or how can I clear out the cache?

We normally get a couple of these issues every week, deleting the local profile has been a quick fix in the past. In the last couple of days the number of reported instances of this issues has exploded. It seems to be a very sporadic issue affecting some students on some machines. We've gone as far as to move the affected user and computer to an OU with no group policy being applied to it and even after multiple runs of gpudpate /force we are seeing the same behaviour - it's like something is getting hung up on the machine, even deleting this users local profile isn't fixing it.

We've tried a couple of hotfixes from Microsoft (KB2610379 and KBKB2775511) both of which haven't helped.

We've proved that re-imaging the machine does fix it but giving the number we are seeing this isn't really practical and ideally I would like a fix to stop it happening in the future.

Just wondering if anybody ever managed to solve it?
