How Do I Configure Network Connection Between Workspace Application Streaming and the Windows AD?

Scenarios

When the Windows AD is deployed on the enterprise intranet or in the same VPC as Workspace Application Streaming, you need to configure the network connection between Workspace Application Streaming and the Windows AD.

Prerequisites

You have obtained the domain administrator account and password.

Procedure

Scenario 1: Deploying the Windows AD in the customer's data center intranet

Figure 1 Deploying the Windows AD in the customer's data center intranet

1. Use Direct Connect or IPsec VPN to connect the customer data center to the VPC. For details, see Direct Connect Getting Started or VPN Administrator Guide.
2. If a firewall is deployed between the Windows AD and the cloud application, enable the following ports on the firewall for successful connection, as shown in Table 1.

   Table 1 Port list

   Role	Port	Protocol	Description
   AD	135	TCP	Port for the Remote Procedure Call (RPC) protocol (LDAP, DFS, and DFSR)
   	137	UDP	Port for NetBIOS name resolution (network login service)
   	138	UDP	Port for the NetBIOS data gram service (DFS and network login service)
   	139	TCP	Port for the NetBIOS-SSN service (network basic input/output)
   	445	TCP	Port for the NetBIOS-SSN service (network basic input/output)
   	445	UDP	Port for the NetBIOS-SSN service (network basic input/output)
   	49152-65535	TCP	RPC dynamic port (This port is not hardened and opened on AD. If it is hardened on AD, ports 50152 to 51151 need to be enabled.)
   	49152-65535	UDP	RPC dynamic port (This port is not hardened and opened on AD. If it is hardened on AD, ports 50152 to 51151 need to be enabled.)
   	88	TCP	Kerberos key distribution center service
   	88	UDP	Kerberos key distribution center service
   	123	UDP	NTP service
   	389	UDP	LDAP server
   	389	TCP	LDAP server
   	464	TCP	Kerberos authentication protocol
   	464	UDP	Kerberos authentication protocol
   	500	UDP	isakmp
   	593	TCP	RPC over HTTP
   	636	TCP	LDAP SSL
   DNS	53	TCP	DNS server
   	53	UDP	DNS server

3. After the configuration is complete, check whether the networks and ports are working properly by referring to Verification Method.

Scenario 2: Deploying the Windows AD in another subnet of the VPC where the cloud application is located

In this scenario, you need to add security group rules for the Windows AD and open some ports of the Windows AD to the cloud application so that the cloud application can connect to the Windows AD.

Figure 2 Deploying the Windows AD in another subnet of the VPC where the cloud application is located

1. Create a security group in the VPC.
2. Add an inbound rule to the security group.
3. After the security group is created, apply the security group to the Windows AD management server instance so that the cloud application can communicate with the Windows AD.
   NOTE:

   To minimize the number of open ports and protocols, you can add multiple inbound rules to a security group and enable only the ports and protocols listed in Table 1.

4. After the configuration is complete, check whether the networks and ports are working properly by referring to Verification Method.

Verification Method

1. Check the firewall or security group settings of the AD server and ensure that ports in Table 1 are enabled.
   NOTE:

   For details about the port requirements of the Windows AD server, see Active Directory and Active Directory Domain Services Port Requirements.

2. Use the ECS service to create a Windows OS instance in the VPC where the APS is located and add the instance to an existing domain.
   NOTE:

   For details about ECS configurations and operations, see ECS User Guide.

3. Use an RDP client tool (such as mstsc) or VNC to log in to the Windows instance.
   1. Download ADTest.zip to the Windows instance and decompress it.
   2. Press Shift and right-click the blank area of the folder where ADTest.exe is located, and choose Open command windows here from the shortcut menu.
   3. In the displayed CLI, run the following command to check the connectivity of the Windows AD management server:

      ADTest.exe -file ADTest.cfg -ip IP address of the Windows AD -domain Domain name of the Windows AD -user Domain administrator account

      In this example, run the following command:

      ADTest.exe -file ADTest.cfg -ip 192.168.161.78 -domain abc.com -user vdsadmin

   4. Enter the password of user vdsadmin.
   5. Check whether all the returned test results are SUCCEEDED. If FAILED is displayed, check the AD management server configurations or firewall ports as prompted.
