Windows server 2012 r2 ошибка 20499

Hello

We recently did a migration of our RDS Server to a brand new Windows 2012 R2 server.

All was working fine but we started to have this messages in the RemoteConnectionManager event log:

Log Name:      Microsoft-Windows-TerminalServices-RemoteConnectionManager/Admin
Source:        Microsoft-Windows-TerminalServices-RemoteConnectionManager
Date:          9/14/2016 8:42:53 AM
Event ID:      20499
Task Category: None
Level:         Warning
Keywords:     
User:          NETWORK SERVICE
Computer:      XXXXX.com
Description:
Remote Desktop Services has taken too long to load the user configuration from server

</Event>

Everytime this error message is logged the user gets disconnected from their RDS session.

So far we tried the following:

— Validate AD health (sites,subnet,replication, sysvol)

— We changed the DisableTaskOffload option as suggested in other posts

— We verified the group policy settings applied

Unfortunately we still haven’t found what the root cause of this issue is.

Any suggestion of similar previous experience is welcome.

Thanks in advance!

　　我們的遠端連線伺服器 (Windows Server 2012 R2) 只要有使用者連進去，事件紀錄就出現一筆 20499 的警告：

「遠端桌面服務」花太長的時間從伺服器 aaa 載入使用者 bbb 的使用者設定

　　一開始找到的文章都是說要做 DisableTaskOffload 這個動作，但是這動作在我的情況無效，接著在微軟論壇的 這篇 文章，除了 DisableTaskOffload，有些網友告知可以關閉 User 端遠端連線的剪貼簿、印表機及磁碟機等資源，或者從 AD 端帳戶的「環境」頁面去關閉前述資源，但這方式對我依然無效。該篇文章的討論串持續數年，最後總算出現微軟提供的解決方法：

◎ 執行 regedit，找到下面的機碼 (二選一)，：

HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindows NTTerminal Services
HKEY_LOCAL_MACHINESystemCurrentControlSetControlTerminal ServerWinStationsRdp-tcp

◎ 新增一組名為 fQueryUserConfigFromLocalMachine 的 DWORD，並設為 1。

完成後再進行連線就不會再出現 20499 的警告了。
