We have a Windows 2003 server that has user login scripts that include the netuse commands to map shared drives. Some of these drives exist on Windows Server 2003 machines and some on Windows Server 2000 machines. These have worked for years on workstations with Windows XP, connecting all of the drives at logon. I have just joined two Windows 7 workstations to our LAN and the scripts are not completely working. Some of the drives connect while others don't. There seems to be no rhyme nor reason to the connection problem; sometimes the S: drive connects (Windows Server 2003) and the F: drive doesn't (Windows Server 2000). Sometimes it's just the opposite. Sometimes none of them connects. So, I deleted one of the scripts and mapped the network drives manually in the Explorer, choosing "reconnect at logon". Same problem. However, on both machines, one with the script and one manually mapped, if I open the Explorer after receiving the message that Windows can't reconnect all network drives and click on each of the disconnected drives, they then connect. What's happening???

You will need to go to the Windows 7 Support forums at the following link for help with troubleshooting your problem: http://social.technet.microsoft.com/Forums/en/category/w7itpro/Andre Da Costa http://adacosta.spaces.live.com | http://www.activewin.com | Microsoft MVP

Hi, This behavior is caused by the default policy setting in the Windows Server. Mapped Drive Connection to Network Share May Be Losthttp://support.microsoft.com/kb/297684 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. Thanks, Novak
