Identify and fix network connectivity issues
To resolve this issue, identify and fix any network connectivity problems by doing the following:
- Determine if there is a network connectivity problem by using the ping command.
- Perform additional troubleshooting steps, if necessary, to help identify the cause of the problem.
To perform these tasks, refer to the following sections.
Note: The following procedures include steps for using the ping command to perform troubleshooting. Therefore, before performing these steps, check whether the firewall or Internet Protocol security (IPsec) settings on your network allow Internet Control Message Protocol (ICMP) traffic. ICMP is the TCP/IP protocol that is used by the ping command.
To perform these procedures, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.
Determine if there is a network connectivity problem
To determine if there is a network connectivity problem:
Click Start, click Run, type cmd, and then click OK.
At the command prompt, type ping server_FQDN, where server_FQDN is the fully qualified domain name (FQDN) of the Remote Desktop Session Host (RD Session Host) server (for example, server1.contoso.com), and then press ENTER.
If the ping was successful, you will receive a reply similar to the following:
Reply from IP_address: bytes=32 time=3ms TTL=59
Reply from IP_address: bytes=32 time=20ms TTL=59
Reply from IP_address: bytes=32 time=3ms TTL=59
Reply from IP_address: bytes=32 time=6ms TTL=59
At the command prompt, type ping IP_address, where IP_address is the IP address of the RD Session Host server, and then press ENTER.
If you can successfully ping the RD Session Host server by IP address, but not by FQDN, this indicates a possible issue with DNS host name resolution.
If you cannot successfully ping the RD Session Host server by IP address, this indicates a possible issue with network connectivity, firewall configuration, or IPsec configuration.
Perform additional troubleshooting steps
The following are some additional troubleshooting steps that you can perform to help identify the root cause of the problem:
- Ping other computers on the network to help determine the extent of the network connectivity issue.
- If you can ping other servers but not the domain controller, try to ping the RD Session Host server from another computer. If you cannot ping the RD Session Host server from any computer, first ensure that the RD Session Host server is running. If the RD Session Host server is running, check the network settings on the RD Session Host server.
- Check the TCP/IP settings on the local computer by doing the following:
- Click Start, click Run, type cmd, and then click OK.
- At the command prompt, type ipconfig /all, and then press ENTER. Make sure that the information listed is correct.
- Type ping localhost to verify that TCP/IP is installed and correctly configured on the local computer. If the ping is unsuccessful, this may indicate a corrupt TCP/IP stack or a problem with your network adapter.
- Type ping IP_address, where IP_address is the IP address assigned to the computer. If you can ping the localhost address but not the local address, there may be an issue with the routing table or with the network adapter driver.
- Type ping DNS_server, where DNS_server is the IP address assigned to the DNS server. If there is more than one DNS server on your network, you should ping each one. If you cannot ping the DNS servers, this indicates a potential problem with the DNS servers, or with the network between the computer and the DNS servers.
- If the RD Session Host server is on a different subnet, try to ping the default gateway. If you cannot ping the default gateway, this might indicate a problem with the network adapter, the router or gateway device, cabling, or other connectivity hardware.
- In Device Manager, check the status of the network adapter. To open Device Manager, click Start, click Run, type devmgmt.msc, and then click OK.
- Check network connectivity indicator lights on the computer and at the hub or router. Check network cabling.
- Check firewall settings by using the Windows Firewall with Advanced Security snap-in.
- Check IPsec settings by using the IP Security Policy Management snap-in.
To verify that RemoteApp and Desktop Connection is configured correctly, you should start a RemoteApp program that is published by using RemoteApp and Desktop Connection.
To start a RemoteApp program that is published by using RemoteApp and Desktop Connection:
- On a client computer, click Start, point to All Programs, point to RemoteApp and Desktop Connections, point to Enterprise Remote Access, and then click a RemoteApp program.
- Verify that the RemoteApp program opens successfully.
