Data recovery from a damaged VHDX disk.

Had a situation with a VM that turned corrupt after been unfrozen. My feeling is this was the dreaded ODX issue.

The VM would boot and BSOD with Unmountable_Boot_Volume. Tried to mount the VHDX on the Hyper-V hosts and run a chkdsk /r but this wouldn't repair.

Veeam came to the rescue to recover the VM but the data was 36 hrs out of date.

We managed to recover the files by using this software.

Highly recommended.

Had a situation where a NIC in a Dell Server would only negotiate 100Mbps. Turns out it was a dodgy network cable, but in the process I reapplied the Broadcom firmware on the NIC.

I had removed the NICfrom the LBFO team as part of the troubleshooting. After we found it was the cable I needed to add the NIC back to the NIC team.

When I tried I kept getting this error below:

Turns out that the firmware reflash had reset all the NIC advanced settings. Including the Jumbo frame configuration.

Set-NetAdapterAdvancedProperty -Name NIC1 -RegistryKeyword “*JumboPacket” -Registryvalue 9000

After I reconfigured the Jumbo Frame on the NIC it worked!
