Problem:
You have added a computer to a security group and are maybe trying to apply this to a group policy but Security Filtering on a gpresult /r shows that the computer is not in the group. How do we get it added without a reboot?
Solution:
The way to resolve this is in a simple command.
First run this command to show all your existing computer TGT sessions:
klist.exe sessions | findstr /i %COMPUTERNAME%
Then run this command to show all cached updates:
klist.exe -li 0x3e7
Then run this command to clear all the cached TGT sessions:
Windows Server 2016 – Windows Server 2022
klist –li 0x3e7 purge
Windows Server 2008 R2 – Windows Server 2012 R2
klist -lh 0 -li 0x3e7 purge
Now simply run the below command to get your new group memberships:
gpupdate /force
