For Gentle Dental World seems like Credentials from CRM don't work, and they have 2 domains now? I get login failed, anyone knows about it?

# Fix LogMeIn login failed error 1326 when office changes domains

## Problem
LogMeIn Remote Control connection to host "GENTLE DENTAL WORLD – SVR19" fails with error 1326. The login dialog shows multiple domain options (DCA, GSDA, SVR19) in the dropdown, but authentication fails regardless of domain selection. Previously working credentials from CRM no longer authenticate successfully. This typically occurs when an office has been sold or transferred and domain authentication has been revoked for external support access.

## Resolution
1. Verify the office's current ownership and support arrangement status
2. If the office was sold or transferred and support access was intentionally revoked, send notification email to the office informing them that remote monitoring and backup services are no longer available
3. Remove the office from active monitoring systems to prevent continued failed connection attempts
4. Update CRM records to reflect the change in support status

No technical fix is available when domain access has been intentionally revoked by the office or new ownership.
