Resetting the TCP settings in Windows 7 (& probably Vista etc.)

Submitted by donmc on Mon, 01/02/2012 - 17:37

It's hard to admit this, but I have had a great deal of trouble with Windows 7 and VPN - connecting to a remote VPN service from a Win7 Desktop.

I looked everywhere to try to resolve it, when I finally ran across this little gem:

netsh winsock reset catalog [resets winsock]
netsh int ip reset reset.log hit [resets the TCP/IP stack]

Run these two at the command line, REBOOT, and (at least for me) all of my issues with VPN connection failures were GONE !

Settings (in Vista and Windows 7) to access Samba Shares...

Note that NTLMv2 authentication is supported in Samba 3.0+

Seems like we ought to be heading towards Kerberos for all our authentication needs in the longer term.

How to Install Windows 7 to a NEW Drive using an Upgrade DVD

I recently had to deal with Microsoft Support on this issue, and I can save you a great deal of time by passing on this procedure to you. Here's the scenario: you want to upgrade to a new monster SATA drive, and do a clean install of Windows 7 from an UPGRADE DVD, but the way the upgrade is setup, you need to first install the VISTA or XP version of windows so that the upgrade can run without activation errors. Well, I'm told by Microsoft Support that the following sequence will work:
