## 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.
