Event ID 1004 is generated on the Terminal Server

Event ID 1004 is generated on the terminal server every time that a client tries to connect. Terminal Server cannot issue a client license. This error may occur for many reasons. Most of the reasons are not related to licensing.

To rule out a licensing problem, try to connect from the terminal server by using the RDP client. If the RDP client receives a license, a networking problem is probably causing the event. To verify that a networking problem is causing the event, do all of the following:

· Verify the permissions on the MSLicensing key:

HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing

Users need at least read permissions

· Make sure that the following command works:

ping -l 1472 -f <IP address>

· Verify that you have applied the hotfixes that are mentioned in this section. These hotfixes resolve the problem of the expired or old licenses not cleaning themselves up correctly. For more information, see the following Microsoft KB article:
