Tonight I found myself recovering a VM on a Windows 2008 R2 cluster connected to an MD3000i SAN. To make very long and painful story short, it appears that someone applied a series of Windows Updates and then a Dell DSM update that screwed up the multipathing.… [ Continue reading ]

When meeting with a potential customer the other day, she mentioned that she had a running PIX with an unknown password.
I thought I’d refresh my PIX skills and decided to bust out an old PIX 506E we had sitting in the office.… [ Continue reading ]

According to Microsoft, when creating disk partitions, the “Disk Management” MMC snap-in mis-aligns the partition with the underlying physical disk.… [ Continue reading ]
A few months ago, I ran into a problem when copying large files between two tiers of a network in one of our datacenters. I was doing a hardware upgrade on some Hyper-V hosts in a DMZ and was copying the images to a backup server while I swapped out hardware components in the Hyper-V hosts.… [ Continue reading ]
