Resolved Expired Certificate - Windows Small Business Server 2003

Running Windows Small Business Server 2003 SP2 - fully updated.

I recently began receiving this critical error in the system log in conjunction with the "Certificate Services" service stopping - and not wanting to stay started even after attempting to restart it.

"A certificate in the chain for CA certificate 0 for [companyname1].[companyname].local has expired. A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. "

Can anyone advise on a resolution? My searches so far have yielded no solution.

 

Information as requested.
Server name disguised.

Application log error message #1
Certificate Services did not start: Could not load or verify the current CA certificate. mycompanyname1.mycompanyname.local A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. 0x800b0101 (-2146762495).

Application log error message #2
A certificate in the chain for CA certificate 0 for mycompanyname1.mycompanyname.local has expired. A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file. 0x800b0101 (-2146762495).

Additionally - "Certificate Services" will not remain started when restarted. So when opening Certificate Authority control - there is a red dot next to mycompanyname1.mycompanyname.local and no information is accessible because Certificate Services is stopped.

There is an option to Renew CA Certificate - and when opened it states:
Do you want to create a new public and private key pair? The cryptographic service and hash algorithm settings will be preserved. If the existing key length is less than 1024 bits, it may be increased. yes /no?

I have not moved past this yes/no dialogue for fear of blowing something up - my company runs on this its only server and so far - it is still working - albeit with these new error messages every day.

Appreciate any guidance you can supply.

For reasons that are a mystery to me and occurred with no action taken by me - the server seems to have - on its own - without a reboot - after two weeks - created a new CA certificate - called CA Certificate 1 - valid for another 5 years - Certificate Services restarted - and all error messages stopped. Go figure! Problem resolved
