Loss of mapped drive, networked drive disconnects

Q: Loss of mapped drive, networked drive disconnects

I'm running Win7 ult x64. I am running on a network with 4 pcs, 2 vista, 2 xp. We have one server running 2000. I have mapped a couple of folders on the server and can connect just fine when I first start my pc. But after awhile the connection is lost. It still shows the drives, but not the connection. This internet works fine and access is controlled through the server. I can restart my machine and the drives will be connected and working as they should. But after some time they will disconnect again. Win 7 is acting like it is losing the connection to the network, because I can't map another drive from one of the other PC's unless I reboot. But the internet access is still working fine. Any ideas?

Preferred Solution: Loss of mapped drive, networked drive disconnects

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

This behavior is caused by the default policy setting in the Windows Server.

Sometimes firewall can also cause this kind of issues. I suggest you temporary disable the firewall on both computers.
After doing these, the mapped drives should not disconnect.
In general situations, although the connections disconnect after a while, it should be able to reconnect if you launch it. In this case you may need to change the NTLM authentication level. Please refer the following website.
Network security: LAN Manager authentication level
The policy is:
Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Network security: LAN Manager authentication level
Please change “Send LM & NTLM - use NTLMv2 session security if negotiated”.
If your system is Windows 7 Home Premium, you may change it from Registry.
1. Launch regedit from Start Search box.2. Find the following branch. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Create a DWORD key under Lsa and set:
Name: LmCompatibilityLevel Value: 1
4. Restart.Arthur Xie - MSFT

Hello

I have a few computers here in my office that randomly disconnects from the mapped network drive which is on our server. Both computers are operating on Windows XP Professional and the server is running Windows 2003 Server (small business edition). All computers have plenty of RAM (at least 1 Gig each) and are most likely P4 chipsets (one is a brand new Dell Optiplex and the other is no name brand). I did check to see if I have enough licenses on my server, which we have 10 and we have a total of 7 computers accessing the server. If anyone can help me with this issue, please post ASAP so I can get this issue resolved.

Check the PC NIC cards Power Management Setting to make sure the computer is not powering the Lan Cards down.
