Exchange2007 certificates issue: "The name of the security certificate is invalid or does not match the name of the site"

what certificate do you have configured in exchange ?

using the following procedure to change the exchange certificate to mail1.mycompany.com


http://www.sslshopper.com/article-how-to-use-ssl-certificates-with-exchange-2007.html

I am using selfsigned by default created certificated when we install exchange 2007.

certificates*.....

On client side when we view the certificates it say certificate status is ok.

Details:
CN = newserver
DNS Name=newserver
DNS Name=newserver.mycompany.local
Enhanced Key Usage: Server Authentication (1.3.6.1.5.5.7.3.1)
Key usage: Digital Signature, Key Encipherment (a0)
Basic Constraints: Subject Type=End Entity; Path Length Constraint=None
Thumbprint algorithm: sha1


anything i can provide more to solve this issue?

Is this certificate being installed on the Exchange Server? If yes, then don't use the FQDN.
The certificate must match the name of the host where it resides.

Hi,

it seams that problem is with "Subject Alternative Name" field in certificates.
When creating certificate request have you used -DomainName part of command?
You can use it to specify more names for certificate such as...

New-ExchangeCertificate -DomainName newserver, newserver.mycompany.local, mail1, mycompany.local -Services SMTP or something like that

There is usefull link at http://technet.microsoft.com/en-us/library/bb851505(EXCHG.80).aspx 

Here is some more output if tht helps

I think this is the problem ...  issuer is newserver and the certificates are installed with mail1.mycompany.com ...


what else I can look?

agreed with spriggan13 it will be ok if we have
CertificateDomains : {mail1, mail.mycompany.com, newserver, newserver.mycompany.local}
rather than
CertificateDomains : {newserver, newserver.mycompany.local}

how can we work on it ?

Would this be good approach to remvoe the existing certificates and then create and install new certificates?
any secure way to do that?

Hi spriqqan13,

Would you recommend to follow this URL
http://community.spiceworks.com/how_to/show/969

Waiting for a quick response.

Many thanks.

Yes, that procedure should work for you.

Hi,

that link is ok.
 Basically you just need to generate cert the same way you did first time, but with that additional command " -DomainName newserver, newserver.mycompany.local, mycompany.local,  mail1.mycompany.com, autodiscover.mycompany.local " that will include all alternative names.

If im not wrong this should be it.

New-ExchangeCertificate -KeySize 2048
-SubjectName "CN=newserver.mycompany.local, DC=mycompany, DC=local"
-DomainName newserver, newserver.mycompany.local, mycompany.local,  mail1.mycompany.com, autodiscover.mycompany.local
-PrivateKeyExportable $True


Enable-ExchangeCertificate "thumbprint" -services IIS, SMTP, POP, IMAP
