Hi, have a very strange issue and would really appreciate some advice. Windows 7 Enterprise - I have various VPN connections set up on my machine and all are suddenly having the same problem. I can connect to the VPN, I can RDP to any server, I can connect outlook to exchange on the server BUT I cannot map to any shares. I get error Windows cannot access \\xxx.xxx.xxx.xxx\sharename (Error 0x80070035 Network Location cannot be reached) Also, in the system event log I get a NetBT Error - Event ID: 4311 as below: Initialization failed because the driver device could not be created. Use the string "000000000100320000000000D71000C011010000010000C003000000000000000000000000000000" to identify the interface for which initialization failed. It represents the MAC address of the failed interface or the Globally Unique Interface Identifier (GUID) if NetBT was unable to map from GUID to MAC address. If neither the MAC address nor the GUID were available, the string represents a cluster device name. Would be so grateful for any advice on how to fix this - I have tried things such as disabling the firewall and Forefront, clearing the credentials cache, but makes no difference. Many thanks

Just to add... Discovered that I cannot connect to shares even on the local network.
