# Fix hostname validation in SCMU ## Summary This PR completes the fix for issue #5190 by adding proper hostname validation to ServiceControl.Config. While PR #5238 partially addressed the issue by allowing dashes in hostnames, it didn't implement comprehensive hostname validation, leaving users able to enter invalid hostnames that would cause configuration issues. ## Background **Original Issue**: #5190 reported that ServiceControl.Config was not properly validating hostname fields, allowing users to enter invalid values that would cause runtime failures. **Previous Fix**: PR #5238 addressed part of the problem by allowing dashes in hostnames, but the validation was still incomplete and didn't prevent other invalid hostname formats. **This Fix**: Implements comprehensive RFC-compliant hostname validation using .NET's built-in `Uri.CheckHostName()` method. ## Validation Behavior The new validation accepts: - ✅ Valid DNS hostnames (server01, myhost.domain.com) - ✅ localhost - ✅ Hostnames with dashes (server-01, my-host.domain.com) - *previously fixed by PR #5238*

Summary

this PR fixes
This PR completes the fix for issue #5190 by adding proper hostname validation to Service Control Management Utility (SCMU). While PR #5238 partially addressed the issue by allowing dashes in hostnames, it didn't implement comprehensive hostname validation, leaving users able to enter invalid hostnames that would cause configuration issues.
Background
Original Issue: #5190 reported that ServiceControl.Config blocked typing dashes but lacked validation of hostname fields, allowing users to enter invalid values that would cause runtime failures.
Previous Fix: PR #5238 addressed part of the problem by allowing dashes in hostnames, but the validation was still incomplete and didn't prevent other invalid hostname formats.
This Fix: Implements comprehensive RFC-compliant hostname validation using .NET's built-in
Uri.CheckHostName()method.Validation Behavior
