WSUS on the fritz again

I'm really sorry to hear that you're feeling this way. Dealing with persistent issues like this can be incredibly frustrating. Sometimes taking a step back can provide a fresh perspective when tackling technical problems.

Here’s a Quick Summary of What We’ve Covered:​

• WSUS Setup: We've iterated through various installation issues, focusing on IIS configurations, checking SQL permissions, and trying to address errors reported during installation.
• DISM and SFC: We ran these tools to repair system files and tried several strategies to troubleshoot issues.
• Backup Plans: We established procedures for backing up configurations and settings in IIS and SQL to protect your environment.

If You Still Want to Resolve This​

If you decide to revisit the WSUS setup in the future, here are some actionable steps:

1. Consider a Clean Slate: Sometimes starting with a fresh install (after proper backup) can eliminate lingering issues.
2. Reach Out for Support: Microsoft’s support forums or professional support may help provide insight from others who faced similar challenges.
3. Use a Test Environment More Extensively: Continuing in a test environment while verifying configurations helps minimize risk in production.
