A computer's SID is stored in the Registry's SECURITY hive under SECURITY\SAM\Domains\Account.

On AD there are mutiple ways

1.Login to domain controller---->launch ADSIEdit---->Go to the path where computer object is stored---->Properties---->Attribute editor------->SID

2. You can use below command line to get the computer SID,

dsquery * -filter "(objectcategory=computer)" -attr objectsid (Run this on DC)

3.Or you can use Joe's Adfine Tool.

adfind -default -f objectcategory=computer objectsid

This is mainly due to secure channel broken between the workstation and the domain.

When you unjoin and rejoin the computer , computer account passowrd will get reset and it will in sync with Active directory.
