I’m Afraid I Can’t Do That, Dave: When Firewall Upgrades Go Wrong

A client called this morning saying "I clicked on a security alert and now I can't get on the internet..."  Of course, my spideysense said "Ah!  Classic Malware!"

However, when I got on-site, there was no malware on the machine. 

A quick glance over the Autoruns turned up nothing out of the ordinary, MalwareBytes turned up nothing, doing a netsh winsock reset did nothing to improve the situation.

Connecting Macs to a Windows 2003 Server

We have a client with two offices, one is a PC shop and the other is a Mac shop. The enjoy a friendly rivalry and it's up to me to make sure that they play nicely together.

We recently upgraded the servers in Microsoft shop to Windows 2003 and found that the Mac clients could no longer access the shares over the VPN.

Some googling and experimenting later, and we stumbled upon the issue.

(This utility first made its appearance, it seems, as part of the Windows 2000 Resource Kit, and is available as a download from Microsoft.
