WSL Installation Step-by-Step
WSL (Windows Subsystem for Linux) is a very useful way of being able to use Linux tools on a Windows system, making it simple to get a proper, working Linux shell up and running. Now WSL2 makes it a lot faster, having an actual full Linux kernel running.
Fixing Broken Redirected Folders
Redirected folders are a blessing, when they work smoothly and result in thousands of otherwise-unprotected folders being stored on a safe server, backed up and available if a PC fails. They can also be an infuriating mess when they go wrong. I recently tested a new redirected folders setup using a GPO and fresh fileserver.…
Timeout Failure – Veeam Backup Agent
I had a Veeam Agent backup running regularly and successfully. The agent server is a simple Windows Server 2016 file server. One day recently, the backup job simply stopped working. When I manually ran the job, it started OK, it got as far as “Required backup infrastructure resources have been assigned” being green-ticked, and then…
Extremely Slow Windows Server with ReFS
I have recently built a server, simply to use as a large (100 TB) iSCSI host. A low-end but still a Xeon 6-core CPU, 8 GB RAM, and a caching RAID controller driving two arrarys, a couple of boot SSDs in RAID-1 and a RAID-6 data array across 16 SATA disks. This is a decent…
P2V of Remote Desktop Server – Fixing Terminal Services
I have recently done a lot of P2V and V2V work, and have found many things that need tweaks – this one wasn’t well covered by anything I found by Googling, so I thought I’d better document it.
OpenVPN User with New Phone, How to Reset Google Authenticator
We have a pretty standard OpenVPN setup for some of our users. One of them just got a new phone, and although the trasfer brought over his Google Authenticator app and the code still shows, it no longer works with OpenVPN. This article explains how to resolve this.
Exchange Server Information
This information is mostly available elsewhere, but I have done some Exchange upgrades and migrations recently and found it useful to pull it all together into a single page for reference.
Merging and Deleting a Differencing Disk in Hyper-V
Differencing disks do have their uses, as I see it a more permanent snapshot of just the disk. Recently I needed to merge it back into a normal virtual disk. It took a bit of digging, as deleting the differencing disk is not as simple as you might imagine.
How to Fully Reset an NTFS Filesystem
I’ve recently needed to reorganise a very large (>3.5 TB), very complex (millions of folders, tens of millions of files) NTFS filesystem which had been allowed to evolve slowly over the years into a great big mess. Share permissions were a little too liberal, so users of varying technical competence had run riot – applying…
25 Years of DOOM
25 years ago, in late 1993, something happened which changed the world – Doom was released by Id Software. Here I’ll explain why I feel this was a really important step for the PC industry.
