"Found 1 files older than 120 days in" Warning in Windows Server 2019 64 Bit

Everything is working fine but I keep getting this message every day. Since I'm kind of anal, it annoys me :slightly_smiling_face:. It's a PEM file several years old while everything else is up to date. Is this just a leftover file that can be deleted or no? (See screenshot.) Thanks in advance.

Could you please explain how this is related to Let's Encrypt? :slight_smile:


The full path (Wouldn't fit in the title) is...

Found 1 file older than 120 days in "C:\ProgramData\win-acme\acme-v02.api.letsencrypt.org\Certificates"

So, is that error issued after running win-acme?

And, your screen fragment truncated the file name. How is that name different than the more recent one?


Yes, looks like it's set to run every morning. New screenshot...

Oh, its a CSR file. Probably just a remnant from a much older win-acme run.

You could just move it to some other folder and see if it causes any problems. You can always move it back if it does.

I am not an expert on win-acme but you could also ask on their forum. Someone there should know why a file was left behind


OK, I copied the file name into a notepad file, then renamed it. Everything seems ok.

Thanks for the help!

OK, I thought all was well and deleted the file. However, now my TLS on my SMTP server stopped working and I can't turn it back on. The box is greyed out. Any ideas how to fix this?

That seems a better question for an IIS 6.0 support forum. Like this one maybe:



Try disabling TLS:

Then get a new cert before turning it back on.

If that fails, try another forum :frowning:


Unfortunately is already is off, the trouble is turning it back on. All my certs are valid on all my domains. Just apparently not for SMTP but it was fine for years.

In "delivery" click "advanced".
There be sure to put a "fully qualified domain name" that is covered by a local cert.


If you are genuinely running IIS6 (Windows Server 2003) you need to forget about getting this to work and migrate your services to a new operating system. Microsoft support for that OS ended 8 years ago, as you would expect for an OS that's more than 20 years old.


It's Windows Server 2019, (IIS 10) but it still has part of IIS 6 just for the SMTP server. They all do as far as I know, I believe it's packaged with it. I've been on 2012 and 2019 and they both have it.
