MS08-067 RPC Vulnerability

Last night I got the word that our director wanted MS08-067 patched ASAP, so I went into work to patch our servers and develop a script to deploy it to the workstations. We don’t utilize tools such as SCM, and our WSUS deployment isn’t ready for use, so we needed […]

Network Management Solutions

I got to thinking today about how little insight we have in our network at the moment. At one point we operated a plethora of different tools that gave a lot of redundant info scattered in various places, and now it seems like they haven’t been maintained so we have […]

Unexpected Group Policy Behavior

Frustrations with x64 (in)Compatability
