Hello Everyone, I hope you can help. I went to the Buffalo forums and they are clueless... I have several computers (Server 2003 - domain server, XP Pro SP3 and Vista Ultimate - All SPs and updates are installed) I also have a Buffalo NAS device on the network. I can connect to the NAS on the XP machine. On the Vista machine: I can ping the device by name and IP I can use IE to log into the admin console at http://192.168.1.69/cgi-bin/top.cgi Windows Networks can see the device. The buffalo software can see the device. BUT.. When I try to connect to the device through Networks I get this: //LS-QL70A is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permission. I get the same error when I try to connect using NASNavigator2 software from Buffalo. I get the same error when I try to MAP a network drive. Any ideas? I can do all of the above just fine from XP Pro.

From another forum, and pieces from this forum. I have a fix for anyone who cares.. For anyone else that has this type of issue. To resolve the issue, do the following: Set the LAN Manager Authenticaiton level to Send LM and NTLM responses. In the control panel Administrative Tools -> Local Security Policy -> Local Policies -> Security Options --- in the right panel find "Network security: LAN Manager authentication level" double click it and in the pull down I selected " Send LM & NTLM responses" I hope this helps someone else with this issue. I think it happens in Windows 7 also....
