Desperate for Certificate renewal help

[Mr_M_Cox]

Hi All,

 

I have got three expired certs on my server which i need to renew but having done much googleing I cant get it to work.

 

Cert 1

Issued by - domainname-servername-CA

template - Domain Controller

requester name - domain/servername$

 

Cert 2

Same as above but using Web Server template and requester name - domain/administrator

 

Cert 3

Same as Cert 2 but requested by different user.

 

Please help, how do I renew these?

 

Thank you.
