Active directory Certificate Services

[cragos1984]

Hi

 

I have just had a certificate error pop up when trying to access our Cisco Phone system Via the web. I am being told certificates have expired. When I look in active directory certificate services the Enterprise PKI has a big red cross next to it, upon closer investigation it appears that the 5 year CA root certificate has expired. The main problem I have with this is that the server that I take it issued the certificate was decomissioned back in 2012. Does this mean I will have to set the whole lot up from scratch or is there an alternative way around this?

 

Apologies if I haven't given enough information or detail but this is the first time I have dealt with certificate services in any way. So any help would be greatly appreciated. also if you need further info to possibly help me out I will try to aquire it

 

Thanks in advance
