Using the CERTREQ command to include a SAN 

Here I am using the CERTREQ command to create a request file that will allow me to obtain a certificate with a DNS entry in the Subject Alternative Name field from the Active Directory Certificate Services CertSrv web page.
[Version]
Signature="$Windows NT$"
[NewRequest]
Subject = "CN=hostname.domain.com" ; Remove to use an empty Subject name.
Exportable = FALSE ; TRUE = Private key is exportable
KeyLength = 2048 ; Valid key sizes: 1024, 2048, 4096, 8192, 16384
KeySpec = 1 ; Key Exchange - Required for encryption
KeyUsage = 0xA0 ; Digital Signature, Key Encipherment
MachineKeySet = True
ProviderName = "Microsoft RSA SChannel Cryptographic Provider"
RequestType = PKCS10 ; or CMC.
[Extensions]
2.5.29.17 = "{text}"
continue = "dns=url.domain.com&"
[RequestAttributes]
CertificateTemplate = MyWebServerCert ; Modify for your environment by using the LDAP common name of the template.
;NOTE: There are four parameters in this file that you need to modify to address your specific needs.
;Subject - This should be expressed as the FQDN of server or URL. EX: "CN=hostname.domain.com"
;Exportable - TRUE or FALSE depending on the requirement.
;_continue_ - This should be expressed as the FQDN of server or URL. EX: continue = "dns=url.domain.com&"
;Additional SANs can be included as needed in this same manner.
;CertificateTemplate = MyWebServerCert, this must match the name of the certificate you select in the pull-down from certsrv
