Hey there!! I Have a Server 2019 on VM running RDS with approx 20 users. Server is part of a domain. ADDC is on another VM running DNS. Server is in a pool with 4 other servers on domain. Users log in and access on premise hosted CRM, email, Teams and O365 apps via RDS. They also need to access a couple of web portals used via Google Chrome browser. Internet speed is fine and general browsing is not an issue, except for 3 websites that are all hosted in Germany. The sites time out, refuse connection and are very very slow when they actually do work. When i say slow, a 200KB pdf service manual can take minutes to download.
If the user minimised RDS session, and uses desktop PC or laptop, these German websites work perfectly everytime. The Desktop/Laptop PC's are not domain connected. I should add that this is Located in Australia.
I have setup google DNS forwarder in the DNS on management server but it makes no difference. This issue is something I have never seen in over 20 years of I.T.
Please throw some ideas at me. What am I overlooking?
