Dear All our office have echange 2010 server and have 2 DC that OS is windows 2008 but domain and forest is 2003, yesterday DC01 that is FSMO and Cert server mainboard is broken, so I promote DC02 to FSMO and Cert server, I can export root cer and Cert db server from DC01 and import to DC02 but I see on EMC all exchange server that have status of exchange certificate is "The certificate status could not determined because the revocation check failed" please tell me how to fix it. I used exchange CA for IIS and SMTP

Hi, Can you check within the Exchange certificate wich CRL lists are used? Maybe they are reffering to the CRL list published on your DC01. Regards, Bart TimmermansKPN Consulting - Technical Consultant www.bart-timmermans.nl

Dear Bart Thank you for your help, and please tell me how to check CRL list

Hi, If you double click on the certificate you can go to the tab Details and scroll down to CRL distribution points. Take a look at the attached image. KPN Consulting - Technical Consultant www.bart-timmermans.nl

Dear Bart sorry that respond to you late, I check CRL it still remember CRL server that old domain controller and can not edit, What is next step

Hi there, I believe the questions is more about Cert server, so I'd suggest you pose it in the server forum here: http://social.technet.microsoft.com/Forums/en-US/category/windowsserver/ Your understanding would be appreciated. Fiona Liao TechNet Community Support
