SYMPTOMS
When you attempt to connect to a Terminal Services-based server that is in Remote Administration mode, you may receive the following error messages:

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

-and-

The system cannot log you on (1B8E). Please try again or consult your system administrator.



CAUSE
When a Terminal Services-based server is running in Remote Administration mode, there is a maximum connection limit of two sessions. Active and disconnected sessions are calculated in this connection limit; the Administrator account is not exempt from this connection limit. The console session, however, does not count against the connection limit.



RESOLUTION
To resolve this issue:
 * 1) Log on to the Terminal Services-based server locally.
 * 2) Click Start, point to Programs, point to Administrative Tools, and then click Terminal Services Manager.
 * 3) Click the appropriate Terminal Services-based server. Note the Users Tab in the right pane.
 * 4) If there are two remote sessions, right-click one of the users with a Remote Desktop Protocol (RDP) session, and then click Logoff. (A reset also accomplishes this goal, but does not save profile changes.)

If you cannot gain access to the console on the Terminal Services-based server, you may have to ask someone to log off. If there are disconnected sessions, you can log on to those sessions.

If you cannot access the local console, you can run the Terminal Services Administration tool from another computer. Using an Administrator account in the domain, click Start, click Run, type \\ \c$, and then click OK. Open the Winnt\System32 folder, and then double-click Tsadmin.exe. In Terminal Services Administrator, click your server, and then click the Sessions tab. Right-click the disconnected session, and then click Reset.

NOTE: All data not saved in this session will be lost.



STATUS
This behavior is by design.
