Troubleshooting Remote Desktop Connection
TS & RDC Printing issues

Black screen while connecting to TS

Cause: 1. MTU size may be too high. 2. you may have a print driver problem. 3. The profile is corrupted. 4. Some programs are running in the background.

"Because of a network error, the session will be disconnected. Please try to reconnect"

Resolution: this issue occurs because the administrator has specified a maximum connection limit, and the limit has been reached. To modify the limit, go to MMC>Terminal Services Configuration>Connections, double-click a connection, i.e. RDP-TC, then select the Network Adapter tab. At the bottom of this tab, change Unlimited connections and Maximum connections.

Can access TS on ISA by using RDC but not TSWeb

Open the port 80. RL062004.

Can't access TSWeb from the Internet

Symptom: you can access TSWeb internally but not from the Internet.

Resolution: make sure all ports are opened.

Can't access TS after installed ISA.

To allow access to TS on ISA from the external interface, you may need to edit the packet filter to open the port 3389. Refer to RL062004.

Client can't logon

SYMPTOMS: After a TS client loses the connection to a Terminal Server, the client can't logon the Terminal Server and the TS shows the client still connects to the server. Resolution: Open Terminal Services Configuration in Administrative Tools, double-click RDP-Tcp in the Connections folder and click the Sessions tab. Click to select Override user settings and check Disconnect from session, and select 5 minutes or so.

Errors: The license will be expired in x days message even you had the license installed.

"No TS licensing server error when run TS license manager".

"The remote session was disconnected because the local computer's client access license could not be upgraded or renewed"

Causes: Installed the TS licenses incorrectly. Refer to case: 0204RS.

Event ID: 1111, 1105 and 1106 - Local printer on TS issues

Causes: TS doesn't have the local printer drivers or can't redirect the local printer.

I can't reconnect after disconnecting

By default, the TS timeout settings are 120 minutes for Connection, 10 minutes for Disconnection, and 30 minutes for Idle. If a client disconnects (rather than logging off), the session is not terminated. Rather, it is held in memory so that the client can't reconnect and re-establish the session. To fix this problem, you need to change timeout settings in TS Connection Configuration.

"The local policy of this system does not permit you to logon interactively."

Symptoms: When trying to connect to a W2K domain controller running Terminal Services with Application Server mode for user access, you as a TS user may receive "The local policy of this system does not permit you to logon interactively" message. You may not receive this message if you logon with a member of the following default groups:

Account Operators
Administrators
Backup Operators
Print Operators
Server Operators
Others based on services on the computer such as TsInternetUser

Also, you will not receive this message when you logon member and stand-alone servers since they have the users group included in the "Log on Locally" user right.

Resolutions:This issue occurs because the W2K domain controller running Terminal Services does not have the Users, Authenticated Users, or Everyone global group added to the Group Policy Object for the "Log on Locally" user right. "Log on Locally" is a required user right in Microsoft Windows NT 4.0, Terminal Server Edition and Windows 2000 Terminal Services. To modify the Group Policy Object for the domain controller, go to Administrative Tools>Domain Controller Security Policy>Security Settings>Local Policies>User Rights Assignment>Policy>Log on Locally>Add>Browse, click the appropriate group, and then click Add. After modifying the Group Policy, type `secedit /refreshpolicy machine_policy /enforce`at a command prompt, press ENTER, and then press ENTER.

"You do not have access to logon to this Session"

Symptoms: When trying to connect to a W2K server running Terminal Services with the Remote Administration, you may receive "You do not have access to logon to this Session" message.

Resolutions: this issue occurs because W2K server running Terminal Services with the Remote Administration mode do not permit users to logon by the default. Only two concurrent administrator accounts for server management can connect to a W2K domain controller running Terminal Services configured to use Remote Administration mode.

"Your interactive logon privilege has been disabled. Please contact your system administrator"

Resolution: use Active Directory Users and Computers to modify this setting. To do this, open Active Directory Users and Computers, check "Allow Logon to terminal server" box under the Terminal Services Profile tab of the user account.

"The terminal server has exceeded the maximum number of allowed connections"

Causes: 1) the server has reached its connection limit. Note: Terminal Servers in Remote Administration mode allow a maximum of 2 concurrent sessions. 2) there are some unused session need to be logoff.

"Terminal Server sessions disabled. Remote logins are currently disabled"

Resolution: this issue occurs because the administrator has disabled logon by issuing the CHANGE LOGON /DISABLE command. In order to to enable logon, use the CHANGE LOGON /ENABLE command.

"The client could not connect to the Terminal server. The server may be too busy. Please try connecting later"

Symptoms: 1. When trying to access TS (administration mode), you may get this message: "The client could not connect to the remote computer. Remote connections might not be enabled or the computer might be too busy to accept new connections...."

2. Under TS Manger, it shows Console only and not RDP-Tcp (listener).

Resolution: 1. Make sure that Remote Desktop is enabled
2. Reset connection
3. Reboot the server.

For consultants, refer to cannot connect to TS page.

TSWeb connect is grayed out

Q: I have been using my Desktop to access our TS via TSWeb. Now, I received a new laptop. When I try to access the TS using tsweb, the Conenct tab is grayed out and I can't access the TSWeb. Why?

A: You need to install Remote Desktop ActiveX Control. If you don't have rights to do so, have your administrator install it for you.

Q: Why am I unable to control another XP by using Remote Assistance?

A: To take over the control the remote XP computer, click the Take Control on the top right.
