Windows 7 clients - 2003 server - Unable to connect to share using host name...sometimes
Hi all, I have recently taken the plunge and purchased 3 new Windows 7 PCs in a domain which has been entirely XP and a spattering of 2000 clients up until now. The Windows 7 PCs have connected to the domain just fine but initially my link between the mapped drive on H: and Documents wasn't working. I fixed this by changing 'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal' to 'H:'. this sometimes works but often the user will get a message that says 'H: refers to a location that is unavailable'. The drive won't open. Even if I reset the registry key above back to %USERPROFILE%\Documents and restart it doesn't necessarily make a difference. The H: drive is mapping to (using user 'newpc' as an example) \\thsdc01\home$\newpc If I connect via the IP address it works fine. Also I can connect to other shares using host name. While typing this message the computer that currently has the problem (it can be any one of the three) has started working again! Very unusual. The share permissions are everyone full control so that shouldn't be a problem. Any help appreciated. Alternative is that I will put XP onto them.

I suggest you disable the firewall on both computers. If the issue still occurs, try to change the NTLM authentication level. Network security: LAN Manager authentication level http://technet.microsoft.com/en-us/library/cc738867(WS.10).aspx 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”.Please 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.
