During these days we faced problems on license server (that was dealing 2008 R2 CAL)
Error was this one:
Event ID 4105: The Terminal Services license server cannot update the license attributes for user <UserName> in Active Directory Domain <DomainName>
Log Name: System
Source: Microsoft-Windows-TerminalServices-Licensing
Event ID : 4105
Level: Warning
User: N/A
Computer: <computer name>
Description:
The Terminal Services license server cannot update the license attributes for user <user name> in the Active Directory Domain <domain name>. Ensure that the computer account for the license server is a member of Terminal Server License Servers group in Active Directory domain <domain name>.
If the license server is installed on a domain controller, the Network Service account also needs to be a member of the Terminal Server License Servers group.
If the license server is installed on a domain controller, after you have added the appropriate accounts to the Terminal Server License Servers group, you must restart the Terminal Services Licensing service to track or report the usage of TS Per User CALs.
Win32 error code: 0x80070005
Solution was to add these AD group "Terminal Server License Server" to users that was dealing with problem (and changing permissions as below screenshot)
