You need to recreate a new computer account. It appears to be a SID issue.
Info below pulled from:

The error, and subsequent 'bad behavior' are because the domain has a
new sid for the workstation, while the worstation is utilizing the old
sid. The fix is easy, however.

First, log on locally to the workstation, with the local admin
account. Then, remove the workstation from the domain by joining it
to a workgroup. The name of the workgroup doesn't matter, so long as
it removes itself from the domain. You should get a window saying
"Welcome to the xxxx workgroup!". You'll have to reboot the
workstation for the changes to take effect.

To ensure that the machine is removed from the domain, go to a
workstation or server that has the AD User and Computers snap-in.
Ensure that POS04 is not present. If it is, delete it. wait 12
minutes to ensure replication to all GC's, if you are in a large

Now, go back to the workstation, logging on as local administrator.
Join the machine back to the domain, utilizing an account that has
sufficient privileges.
