Good morning,

Following the extended weekend and the return of several users, the PCs in our network performed WUA searches (the first time in several days/two weeks). A portion of them (10-20 out of approximately 200 PCs) are displaying errors with messages like this:

After some searching on the forum, it seems to be a matter of clearing the cache. I haven't tried the commands given yet (thread from 2023). Is this still the way to fix this problem? Isn't there a way to prevent it from happening again?

Sincerely,
