[SOLVED] Unable to perform update (0x800703f1)

subbynetty · Mar 2, 2023

Hello Sysnative! I just built a home virtual machine lab and I am having issues with this one Windows 2016 machine as updates keeps on showing as "Configuration Registry Database is corrupt". I would appreciate it if anyone can assist checking if the following SCHEMA.DAT file is in shape please? I just needed this one file and if this is still not working then I will just rebuild the virtual machine (the reason as to why I am still holding onto it is because I really wanted to fix it if possible and maybe learn a thing or two along the way).

SCHEMA.DAT

Thank you!

Hi,

Here is the repaired SCHEMA.dat file, could you please upload a copy of the CBS folder for me? Just to look at the given error.

Maxstar.. you are a STAR! You are a legend!!!! I have promptly donated with what I have at the moment! Thank you very much for the prompt response! This has fixed my issue and I can now proceed with the updates. Unfortunately, I am having issues pulling out CBS Log file from the home VM I created (might be something to do with vmware tools as I tried to also check for any driver issues) hence I can't provide one.

For future reference, Is there a way I can possibly repair the file on my end? I understand that this may have to do with HEX editing.

PS. what I tried is to boot another windows server 2016, placed the corrupted SCHEMA.DAT on C:\Windows\System32\SMI\Store\Machine (renamed the existing one to .BAK file), load the corrupted SCHEMA.DAT file on the registry hive under HKLM\SCHEMA. This seems to "changed" the file but I am not sure if it did repaired it as it has a different structure than that of which you uploaded.

I'm still having issues copying the CBS log file, but I did my best typing the error I found below (it was having issues with the SMI Schema Hive, hence I asked if the SCHEMA.DAT file can be repaired)

C++:

Hmm, that's odd, are you sure it was the corrupted hive? I tried what you did, but was not able to load this hive on one of my Server 2016 VM's.

Yeah, but I can confirm that Windows Update now works after I replaced it with the SCHEMA file you provided. So all good now! Thank you again!
