Real-world Citrix, Azure Virtual Desktop, and end-user computing knowledge from a Senior VDI and EUC Consultant based in Switzerland. Posts here are war stories from production, script fixes, and design decisions that came out of 15 years of consulting engagements across the DACH region.
Every post is grounded in an actual customer problem, worked end-to-end. Vendor documentation gets you the happy path, real environments break in ways the docs never cover, and these are the writeups that come after the fix has landed.
After a Windows update on the vDisk, older Citrix PVS targets on VMware refused to boot with LoadImage error: Access Denied. The vDisk was fine, the Secure Boot keys in each VM's NVRAM were not.
IGEL calls it Native USB Redirection, Citrix calls it Generic USB. Here is when to use it, when client drive mapping or an optimized HDX channel is the better choice, and how both sides must be configured.
After an IGEL OS 12 migration, Citrix Workspace app stayed signed in after the session ended. Post-session Logoff closed the gap but froze the thin clients. The automatic soft-logoff timer is the cleaner fix.
How I turn EUC troubleshooting sessions into a knowledge base that answers the next question. Three layers, a strict human gate, and why every note is plain markdown in git.
HDX connection time should be a couple of seconds. When it is 15 to 20, the transport negotiation is failing and every user pays for it on every launch. How to read it, why it happens, and what to do.
StoreFront and NetScaler get renewed. The Cloud Connectors hold a bound certificate too, and netsh will refuse to add it a second time.
Three lines in FSLogix redirections.xml took SAP Business One launch times from ~2 minutes to ~1 on non-persistent Citrix VDAs. The Copy=3 attribute is the underused trick that makes it work.
Citrix file-based licensing goes end of life on April 15, 2026. Environments that haven't migrated to LAS will stop working. No grace period.
How I built this blog with Claude as an AI pair programmer - Jekyll, Chirpy tweaks, and a custom post editor that has since grown OAuth auth, offline drafts, and a one-click draft-to-post promote.
Citrix Director shadowing broke after the January 2026 Microsoft patches. Here's the GPO-deployable msra.exe /offerra workaround - no third-party tools.
