OK, so I tore through all related posts before posting. I have 2 servers in the DMZ. I can reach both via Azure VPN, and both have http endpoints that work fine. I have created and recreated RDP endpoints for both via console and powershell. The last one I built via powershell, finally worked (1 VM only) 5 hours later when double checking. It was working fine the next day till late morning when I simply got booted out while in the middle of a SQL install. Was stopped in the middle of install researching admin passwords (moving existing server from CoLo), so no activity was going on that would make a change to the firewall. I can now no longer reach it and have never been able to reach the other. I have no ACL on either as there is nothing on these boxes. I need to finish getting them configured and the VPN is cumbersome due to some of our environmental constraints (especially for when I pass the servers off to other users).
Any ideas?
