Windows7 not able to access remote 03 Sharepoint sites

We got a call at the IT Support Desk last week regarding an odd issue with Windows 7 not being able to access remote sharepoint sites. After testing on the Vista and XP machines in the office to make sure it wasnt a credential problem, we came to the conclusion that it must be something in particular with the Windows 7 machine.

After about 15 mins of adjusting settings we found out that it is due to issues with WebDAV requiring true SSL Connection.

The fix for this is the following:

Locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
On the Edit menu, point to New, and then click DWORD Value.
Type BasicAuthLevel, and then press ENTER.
On the Edit menu, click Modify.
In the Value data box, type 2, and then click OK.

Note The mapping is as follows:
0 - Basic authentication disabled
1 - Basic authentication enabled for SSL shares only
2 or greater - Basic authentication enabled for SSL shares and for non-SSL shares
Exit Registry Editor, and then restart the webclient service…

Issue with file sharing over VPN.

We had a call on the IT Support desk recently with regards to a VPN issue. TheVPN connects fine and you can ping devices from both sides. But you try to file share to other devices and it wont work

The issue is with the NIC on the client end letting SMB traffic Out, this was found using wireshark and monitoring the IP Packets that were leaving the NIC and entering the Firewall at the other end, and then monitoring traffic on both sides of the client NIC as the traffic getting from the NIC and tat the Firewall was the same.
After looking into why the NIC was not letting the SMB traffic through it was found to be the NETWORK CLIENT FOR MICROSOFT NETWORKS was not installed on the NIC. Once installed it instantly started to work.
