Server 2012 RDP Slow

Hi guys

We recently deployed out serveral servers all running server 2012 at various clients. They are all mostly Dell R410's or Dell R520's.

We have noticed that the RDC connections to these servers are far slower than the connections to our 2003 and 2008 servers that run on the same networks.

We have tried to add the following registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters as mentioned in other support articles but our connection is still slow.

Has anyone else foudn this sort of issue with server 2012 RDP.

I have many Server 2012's deployed and no apparent speed issues with RDP.  I am also using Dell servers, models R710s and R720s.

Have you verified the binding order of the protocols and the NIC order on these servers?  Microsoft default are not the best setup.

1. Go to:  Control Panel > All Control Panel Items > Network and Sharing Center
2. Click "Change adapter settings"
3. hit the "ALT" key once, the file menu will appear
4. click "Advanced" then select "Advanced Settings"
5. On the tab "Adapters and Bindings > Connections area :: make sure you NIC(s) are in the order in which you want them used... Make sure the object "[Remote Access Connections]" is on the bottom.
6. In the Bindings for "YourNicName" section, make sure TCP/IPv4 is above v6
7. On the tab "Provider Order" > Network Providers area :: make sure "Microsoft Windows Network" is first.

Click thru all OKs.  Then give it a test.

Besides Dan recommendations, I will make sure your DNS are working OK.

Also, because you said this issue is only for this kind of server, make sure you have the latest drivers and check all their setting to match your network settings needs.

I don't have those servers but I have experience slow connections on LAN cards if they are not configured properly either at server or switch level.

Good Luck!!!

If networking checks out okay, look at the power settings under control panel.  Make sure you're set to maximum for performance. Balanced or custom can cause some lag time.
