AWS res documentation change

Service: res · 2026-03-28 · Documentation low

File: res/archive/release-minus-3/ug/troubleshooting.md

Summary

Added troubleshooting sections for Active Directory issues and virtual desktop problems, removed custom domain setup troubleshooting

Security assessment

This change expands troubleshooting documentation with new Active Directory and VDI issue categories. While some added items (like AD admin access to Bastion Host) touch on access control, this is routine documentation expansion for common operational issues rather than addressing specific security vulnerabilities.
