Event ID 203 — TS Gateway Server Connections

  • Article

Applies To: Windows Server 2008

For remote clients to successfully connect to internal network resources (computers) through a Terminal Services Gateway (TS Gateway) server, clients must meet the conditions specified in at least one Terminal Services connection authorization policy (TS CAP) and Terminal Services resource authorization policy (TS RAP). TS CAPs specify who can connect to a TS Gateway server and the authentication method that must be used. TS RAPs specify the computers that clients can connect to through a TS Gateway server. Note that a limit can be set on the TS Gateway server to restrict the maximum number of simultaneous client connections.

Event Details

Product: Windows Operating System
ID: 203
Source: Microsoft-Windows-TerminalServices-Gateway
Version: 6.0
Symbolic Name: AAG_EVENT_MAX_CONNECTIONS_REACHED
Message: The number of simultaneous connections to the TS Gateway server has reached the maximum number that was configured by the administrator. The server is therefore not accepting any new connections. The connection attempt by user "%1" on client computer "%2", using the authentication method "%3" has been denied. For information about how to modify the maximum connection limit, see the "Specify the Maximum Number of Allowable Connections for TS Gateway" topic in the TS Gateway Help.

Resolve

Increase the connection limit on the TS Gateway server

To resolve this issue, increase the connection limit on the TS Gateway server.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

Note: For TS Gateway servers that are running on Windows Server 2008 Standard Edition, a maximum of 250 simultaneous connections is supported.

To increase the connection limit on the TS Gateway server:

  1. On the TS Gateway server, open TS Gateway Manager. To open TS Gateway Manager, click Start, point to Administrative Tools, point to Terminal Services, and then click TS Gateway Manager.
  2. In the console tree, click to select the node that represents your TS Gateway server, which is named for the computer on which the TS Gateway server is running.
  3. In the console tree, expand Monitoring.
  4. With the Monitoring folder selected, right-click the Monitoring folder, and then click Edit Connection Limit.
  5. On the General tab, under Maximum Connections, click Limit maximum allowed simultaneous connections to, and then specify a higher value for the number of allowable connections.
  6. Click OK.

Verify

To verify that TS Gateway server connectivity is working, examine Event Viewer logs and search for the following event messages.

To perform this procedure, you do not need to have membership in the local Administrators group. Therefore, as a security best practice, consider performing this task as a user without administrative credentials.

To verify that TS Gateway server connectivity is working:

  1. On the TS Gateway server, click Start, point to Administrative Tools, and then click Event Viewer.
  2. In the Event Viewer console tree, navigate to Application and Services Logs\Microsoft\Windows\TerminalServices-Gateway, and then search for the following events:
    • Event ID 101, Source TerminalServices-Gateway: This event indicates that the Terminal Services Gateway service is running.
    • Event ID 200, Source TerminalServices-Gateway: This event indicates that the client connected to the TS Gateway server.
    • Event ID 302, Source TerminalServices-Gateway: This event indicates that the client connected to an internal network resource through the TS Gateway server.
