Hello,
We're setting up a backup machine for my ISA TMG server that can be used in case of problems with the primary machine. In the past we've setup a Microsoft Enterprise CA and since alls servers are joind into the domain (Windows 2003 servers) , the root CA certificate appears automatically in all servers' Trusted Root Certificates Authorities folder. I'm using some certificates on my ISA server, for example to enable SSL access to OWA on Exchange, so a properly installed and operational CA root certificate is important.
Now on my backup ISA machine it tells me for some strange reason that there is a problem with the CA root certificate : The integrity of this certificate cannot be guaranteed. All other servers in the domain don't have this problem.
I've copied the certificate manually from the primary machine to the backup machine, but still the same problem.
Could it be that ISA is blocking certificate validity checks with the Enterprise CA, and therefore cannot check the integrity of the certificate ?
How can I troubleshoot this issue ?
Thanks for your help.
Regards,
