I recently purchased 2 new Dell PC with Windows7 Home. I upgrade them to Pro and then added to our SBS2008 network. There is Group Policy to map 2 drives across the network. They do not show up on these new computers. They are also not shown in the list of available network drives if I try to manually map a network drive. They do not show up when I do a 'net use' as administrator. I can map the same network location to a different drive letter and that will reconnect on reboots. Tried this but it didnt work: Go to Start>Type gpedit.msc (it is located at C:\Windows\System32\gpedit.msc .) Press enter to open it. Click yes if UAC prompts you. Go to Local Computer Policy> Computer Configuration> Windows Settings> Security Settings> Local Policies> Security Options> Scroll down to "Network security: LAN Manager authentication level" Change it to: “Send LM & NTLM, use NTLMv2 session security is negotiated” Tried: Investigated power saving mode of Network card : no problems there Tried: http://support.microsoft.com/kb/231289 Thoughts?

Hi, Does this issue only occur to the two Windows 7 computers? How about other Windows 7 computers? Meanwhile, I would like to know how you map drives from Group Policy. Do you use Startup script? Currently, please try the following steps to check the result: 1. On the client machines, launch gpedit.msc, go to Computer Configuration > Administrative Templates > System > Logon, "Always wait for the network at computer startup and logon" enabled it and rebooted the Windows 7 clients. 2. If you run script, try the following Local Group Policy setting: Computer Configuration >Admin templates > system > scripts "Run Logon scripts synchronously". Rebooted Windows 7 client machines. Hope it helps. Alex ZhaoPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
