A client asked me for a report that showed who connected to his server on port 3389 via RDP, Microsoft’s Remote Desktop Protocol .

by File in: howto

The Backtrack 2.0 final distribution is probably the finest collection of open source network penetration, security, and auditing tools currently available.

Last week I was trying to help a remote client whose Windows XP machine was really messed up.  More than half of her automatically starting services refused to start at bootup.  They couldn’t be manually started either, system restore was turned off, and she was in a hotel far, far away from any Windows XP […]

Howto: Uninstall the SLES Virtual Machine Driver Pack for Windows on Xen

by File in: howto

Disclaimer: I recently fell off the turnip truck with respect to Xen, the virtualization platform included with SLES 10. All my past virtualization experience has been with VMware or Virtual Server, so this may be blatantly obvious to the rest of the IT world… We are running Groupwise Mobile Server (GMS) on a Windows Server […]
