Upgrading certificate server to win server 2003 SP2

Hello all,

My organisation has a windows server 2003 SP 1 domain controller running

certificate services.

During a previous upgrade to Win Server 2003 SP1, there were quite a number

of issues arising form the upgrade. I am just being curious if there is any

known issue with upgrading a domain controller running certificate service to

service pack 2.

I would appreciate responses from the house on the best way to upgrade the

server without any issue.

Regards

Damola
