# Len's Auto Brokerage — Deskman Crash Triage (2026-06-17) ## User - **User:** Howard Enos (howard) - **Machine:** Howard-Home - **Role:** tech ## Session Summary Becky at Len's Auto reported Deskman would not open on the server. The Windows error report showed a CLR20r3 crash in `gui.exe` (Deskman's .NET front-end, v4.4.2248) with fault module `mscorlib` and exception `System.UnauthorizedAccessException`, on OS version 6.0.6002. Decoded the signature: the box is LAB-SERVER (192.168.1.241), the OLD Windows Server 2008 SP2 machine (EOL), not the new Server 2019 box (LAB-SVR / LENS-SV, 192.168.1.81). The crash was an access-denied condition, initially diagnosed as a likely permissions/ACL problem on Deskman's program or data folder. On the user logging into the server and opening Deskman directly, it displayed "the program is updating." After ~30 seconds, reopening it launched normally. Root cause was therefore transient: the GUI hit files locked/being-written by Deskman's own updater, producing the UnauthorizedAccessException; it cleared once the update finished. No corrupt install, no fix required. Logged the event to the client issue log as a tracking note (explicitly not a ticket). ## Key Decisions - Treated the crash as transient (updater file lock) rather than a corrupt install, based on the observed self-resolution after the update completed. - Did not apply any ACL/permissions fix since the symptom cleared on its own. - Reinforced that the durable priority is migrating Deskman off the EOL 2008 server to the 2019 box, rather than investing remediation effort in the dying server. ## Problems Encountered - Deskman `System.UnauthorizedAccessException` crash on launch — resolved itself after the in-progress Deskman update finished; reopening worked normally. ## Configuration Changes - Modified: `clients/lens-auto-brokerage/docs/issues/log.md` — added a 2026-06-17 entry documenting the Deskman crash, root cause (transient updater lock), and resolution. - Created: this session log. ## Credentials & Secrets - None discovered, created, or rotated. ## Infrastructure & Servers - LAB-SERVER (192.168.1.241) — Windows Server 2008 SP2 (OS 6.0.6002), EOL, WORKGROUP. Currently runs Deskman. To be decommissioned. - LAB-SVR / LENS-SV (192.168.1.81) — Windows Server 2019, current/new server. Deskman migration target. - Deskman GUI: `gui.exe` v4.4.2248, .NET (mscorlib 4.0.0.0). ## Commands & Outputs - Crash signature (Windows error report): CLR20r3 / gui.exe 4.4.2248 / mscorlib / `System.UnauthorizedAccess[Exception]` / OS 6.0.6002. ## Pending / Incomplete Tasks - Migrate Deskman from LAB-SERVER (2008) to LAB-SVR / LENS-SV (2019) — open migration item. - If the crash recurs and does NOT self-clear, fix as permissions: grant the user Modify on the Deskman program/data folder, or relocate its data to ProgramData. ## Reference Information - Issue log: `clients/lens-auto-brokerage/docs/issues/log.md` - Overview: `clients/lens-auto-brokerage/docs/overview.md`
