Dropping Mapped drives

Have you tried "/PERSISTENT:YES" parameter when you apply the "net use" command?

yes i have both in the alternative batch file and my GPO's

.......it sounds to me like they are dropping while a user is logged in and working.....if it was just one user i'd look at the nic/cabling for that 1 machine.......for serveral - 30%- of the network i'd start with a look at the swith these are going to.....

also....is this something that just started?......if so what has changed?......new av?.....windows updates?....etc?

Hi,
Have you seen this - http://support.microsoft.com/kb/297684/en-us

nothing has change, we use WSUS and only on computer group is enabled for update and I am sure its not updates as there 1 of the PC that are in WSUS group is doing the same (Dropping mapped drives) it has SP3 the latest release candidate and the other have a mix of SP3 with a earlier release candidate and SP2. There is a possibility it could be my switches as I have four switches in a bank that has been starting to reboot on there own. I have ordered more but ill the new ones come I have to use these

followed this artical  http://support.microsoft.com/kb/297684/en-us but did not work. log off log on then 2 of the 8 mapped drives are gone.

Drive Mapping is associated with the user.
Is the profile locked? on NT4.0 they called it mandatory profile.
Have you tried one of the users to whom this happens on one of the machines where supposingly it doesn't happen?

so once they map then they stay mapped until reboot/logon/logoff?

try this on one machine and see if it helps......then apply as a gpo if it works

on an xp machine that is  not mapping its drives, open the policy editor by clicking start/run type gpedit.msc and hit enter

drill down to
comp config/administrative templates/system/logon
enable always wait for the network at computer startup and logon

log off/on/reboot

see if it makes a difference

its not just on reboot/log off and log on its also during the time they are working on the pc

its not just on reboot/log off and log on its also during the time they are working on the pc

if it is dropping when they are up and working then that reinforces my thoughts that your problem lies with the switch.....especially since it is multiple users.........do they all connect to the same switch?

No, some are to our 4 by Planet switches and some to our HP switches but I have this horrible thought its my planet switches because. Basically I am the third generation engineer to work on this network and what I can see its like this, we have a Cisco switch where all my servers connect to, from there it connects to the 4 Planet switches that are daisy chained and from connecting to the HP. Ideally I would like it to connect from the Cisco to all the switches and not thought the daisy chained switches to the HP switches.

i have standardize all my network switch but still get the same proble. Now what? i have a feeling its my DNS. can some one please help me with some DNS tools

How many CALs, how is it licensed (per seat or per server), and how many mapped drives per user?

Could be a connection limit issue.

Just to make sure I understand.  User logs on, gets drive "M" mapped to \\server\share.  Then later on if they do a net use the drive mapping does not appear in the list?  Or does it appear and say disconnected?

I agree with wyliecoyoteuk, sounds like a licensing issue.

Please note the "Submit" button requires only a single click.

does not appear in the list. have open licence

What do you mean by "open license"?

How big is "30%" of your network?  Typically how many users do you have with this drive mapped?

sorry if i am bing stuped, i have asked My manager this and he has told me we are ussing volume licence. may be i am just dumb. we i whent onto my licensing i found its been disabled. so corect me if i am qrong, for Windows 2003 R2 do we need CAL's?

Secondly we have about 270 users ussing this map but concurent connections are about 240 as there are some consultants in and out all the time.

It sounds like you are licensed on a per seat basis.  That means that each desktop should have a single CAL to allow it to access each and every server on your network for print and file sharing.

I think you can check to see how you are currently licensed by:

1.      Click Start, point to Settings, and then click Control Panel.
2.      Double-click Licensing.

Check to see which box is checked: "Per Seat" or "Per Dervice or Per User".

I agree that you must have cals on the clients if per seat or on the server if per server........but i also thought that if you did not have these cals that it wouldnt allow you to connect in the first place....

If it per seat and you don't have a CAL it should prevent you from connecting.  What I think (hope) is that they will find the server is configured for per server.

Say you have per server and you have 250 CAL's.  But you have 300 desktops.  The 1st 250 get in, all the rest can't.

Now, say one of the original 250 user (USER001) sits idle for awhile and their connection gets disconnected.  The mapping will stay and the net use command will show that it is just disconnected.  Now somebody (USER251) else can then connect, because when USER001 got disconnected you went down to 249 connected users.  When USER251 connects, this brings you back up to 250 users.  So when USER1 tries to re-connect it will fail, because the server is at 250 and I believe at that point in time the map will be removed.

is there no other way to see license status as my administration account that was given to me to use is ServerOperator, and that account does not have access to it on any one of my DC's (i have 1 PDC and 1 DC) but if i go on any one of my three File servers its set to (Per Device or User) so I assume it should be the same on the DC's. I think we don't have enough cals thats why he has disabled (license logging service) from experiance i would disable this service till i receive my cal's and then set it back to auto once the cals are installed, as a short term solution. could this be my problem that, the particulare service is disabled

It does not matter what the licensing is on the DC, it what the licensing is on the server that has the share you want.

Per device/user means that each device/user needs to have a CAL on their computer and then they can access as many servers in your environment they want.

If a device/user did not have CAL they would not be able to access at all.

After the mapping drops, what error do you get when you attempt to re-map the drive?  Please re-map from the command line use the net use command.

here is the error NET HELPMSG 2250. and i found this http://www.pcreview.co.uk/forums/thread-1871516.php and i followed it to the T no luck. i am going bonkers now.

A 2250 should only happen when the computer thinks the the drive is still mapped, that is it thinks it has a connection, but the connection does not exist.

Are you sure that when you do a net use that the mapped drive does not appear in the list?  Does the share you are mapping to appear in the list but without a mapped drive?

the drive is missing during the cource of the day and some times even when you log on. if i run the batch file it gives me the error and a few seconds later it appears. here is the batch file

Well, with all the mappings being persistent you should not need to do the net use /deletes.

What I would recommend doing is do all of the net deletes first, then pause 2-3 seconds and do the net uses.

It really sounds like you are licensed by server and you don't have enough license.

I will say that doing a net use /delete for a resource that is NOT currently mapped will cause the 2250, so if the drive is not mapped when the script is executed it will get the errors.

will try this for a day or so, but do agree with you about the license issue, but i don;t have access to confirm as my account is only server operator. will let you know

Hi giltjr

gues you were hoping this would be the end well, not working. is it a good idea to run the reg delete entry evry time a pc logs on. i an talking about the one that i have sent you.

Reverted to a MS Expert to come and help with the GPO's as there has been tomany cooks in the pot and i don't have the time to go through all the changed GPO's
