Remote Desktop slow on connection when Remote Gateway and Remote Desktop service are on the Same Server

Question

Remote Desktop slow on connection when Remote Gateway and Remote Desktop service are on the Same Server

Neil Wang 21

I have one server configured both Remote Gateway and Remote Desktop service. If I connect to the remote desktop from outside, it takes a very long time on "Configuring remote session" before getting inside.

However, if I connect to other servers via the remote gateway, it connected in seconds. What's the reason for that?

Hi NeilWang , 

whether your networking connection on the RDGateway uses Internet Protocol Version4 or Internet Protocol Version6. If indeed, remove the IPV6 and try again.
You can check it with Control Panel -> Network and Internet -> Network Connections -> Ethernet Propertities -> Networking
please check the RDgateway server and RDSH version, you can enter "winver" in the windows search box to check.
did you configure roaming profile ,UPD ,fslogix in your rds environment?
so when one user remote logon RDgateway,the user profile will attach RDgateway server.
when you use local account of RDgateway server to remote access RDgateway server ,will the same issue happen ?

please share testing results for better solution to this problem.

Hi Grace,

Thanks for your help. Here're my results:

I'm using user profile disks and store vhds in a separate partition. If I switch off that option, will user data be migrated automatically?

This is a key question to solving the issue. Would you please answer to this question: when you use local account of RDgateway server to remote access RDgateway server ,will the same issue happen ?
In addition, after we log off, the profile goes back to UPD automatically and becomes shared for the next logon use, and then applies to the other session hosts in the same collection.

I couldn't use the local admin account for RDgateway. It was complaining the account/computer was not authorized.

Hi NeilWang ,

Under this circumstance, I suggest that you catch logs by using network monitor or wireshark.
a. when client remote connecting to RDGateway（run network monitor as admin on both client pc and rdgateway and reproduce the issue）
b. when client connecting to the other session host through RDGateway .（run network monitor as admin on both client pc, rdgateway and rdsh server then reproduce the issue.）
And then compare the log results between situation A and situation B to find the differences and the error messages during the procedures. Please pay attention that you must use the same domain account to reproduce your rdp issue.

Hi Grace,

I don't know what I have done, however, I found I remedy this issue after I only allow connections from Network Level Authentication enabled computers. Even if I disable that option later again, the slow connection symptom is gone.

But anyway I think NLA is compatible with most of the clients even back in the XP ages, right?

Hi,

Yes, NLA is compatible with Windows XP （with Service Pack 3）.

To use Network Level Authentication, you must meet the following requirements:
• The client computer must be using at least Remote Desktop Connection 6.0.
• The client computer must be using an operating system, such as Windows 7, Windows Vista, or Windows XP with Service Pack 3, that supports the Credential Security Support Provider (CredSSP) protocol.
• The RD Session Host server must be running Windows Server 2008 R2 or Windows Server 2008.

For more information about NLA, you can refer to this link.

Thanks for the explanation. We should meet all the requirements. The link is expired by the way. But that's ok. If we have new RD servers implemetation in the future, I'll keep an eye on those options and update it here. Thanks again!
