Mapped Drives are Disconnected at log on

use the code below to start at startup or check the box reconnect at log on under the map drives if this does not work use the code below

@echo off

cls

net use d: \\servername\folder

Hope this helps in some way.

To have Windows automatically connect to shares on your Network, we'll need to create a drive mapping (or several if you connect to more than one share).

Drive mappings are great for shares that are password protected since you can setup them up to authenticate automatically.

Start by double clicking on My Computer (XP), or Computer (Vista). Then click on Tools from the menu and select Map Network Drive?
If you know the Computer and Share name, just enter it in the Folder: field using the following format:

\\computername\sharename

Or you can browse for the Computer by clicking on the Browse? button.

To automatically connect during logon, check the box next to Reconnect at logon.

If you want to use a specific letter to map the drive (other than the one selected by default), click on the arrow next to the Drive: field and make your selection.

NOTE: any existing drive mappings in use, will not appear in the drop down list.

For shares that are protected with a password, click on the link in the phrase Connect using a different name

In the Connect As? dialog box, enter the username and password of the remote computer. Make sure you append the Computer name before the username.
Click OK when finished.

When you have completed all the steps, click Finish. to connect and map the drive.

Next time you boot your Computer or logon, the share will automatically connect and create the drive mapping. No need to keep authenticating.

We had an issue where mapped drives were disconnected at logon, on servers that were not in the same location.

We had to adjust the response time on our routers to account for the "are you their" request from the client.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters]

"KeepAliveTime"=dword:00300000
"KeepAliveInterval"=dword:00001000

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters]
The regs key are not there. Do I need to add them. I am running XP Pro SP2. Is that still the right place for the reg hacks?

Its not there for me either, which makes me think that isnt your problem. Here is something else I found on your problem. I don't know if it will help or not. It might if your "Hide and disable all items on the desktop" policy is enabled. Hopefully this link will work. Let me know

I looked at that already and followed the instructions on that and still happens.
I have been trying to solve this for a month.
I left the original question vage becuase meybe someone else had a simple idea that would help. I have done 95% of the issues solving that I have found online and nothing is working. I thought (I know my first mistake) if someone else looked at the problem the may see somehting that I have not. If you keep the ideas coming I'll keep trying but I just need it fix. Thanks for the help!

That is not what I am trying to do in this case. I need the mapped drive not to disconnect when I log off or Lock the computer with . I have a few computers that are having this issue but not all of our computers are having this problem. Do you have any ideas that could help keep the connection connected?? Thanks for you help with this issue that I have.
On a side note I have been looking at this for about a month now And I have tried many different ideas so please keep the ideas coming because mybe I have over look something.
