How to request a new certificate manually with certreq.exe tool ussing a INF file and a SAN

Once a time I was really lost regarding how to get a new cert request from command line and I've found  this command ....this is useful for Windows 2003 Server and Windows 2008 Server.

1.Open a notepad and save as policy.inf and copy the below lines:

Policy.INF file

[Version]
Signature= "$Windows NT$"
[NewRequest]
Subject= "CN =server1.mycompany.com;OU=MyCompany IT;O=My Company Inc;L=Saavedra;S=CABA;C=AR"
KeySpec = 1 
KeyLength = 1024  
Exportable = TRUE
MachineKeySet = TRUE
SMIME = FALSE
PrivateKeyArchive = FALSE
UserProtected = FALSE   
UseExistingKeySet = FALSE
ProviderName = "Microsoft RSA Schannel Cryptographic Provider"
ProviderType = 12
RequestType = PKCS10 
KeyUsage = 0xa0   
[EnhancedKeyUsageExtension]
OID=1.3.6.1.5.5.7.3.1   
[RequestAttributes]
SAN:DNS=name1.mycompany.com&DNS=name2.mycompany.com&DNS=name3.mycompany.com&DNS=name4.mycompany.com&DNS=name4.mycompany.com&DNS=name5.mycompany.com


2. From command line and with Local Administrator permissions, type:

certreq -new Policy.inf c:\certs\server1New.txt

3. Submit the request file to the Certificate Authority (CA) and have the CA generate the certificate

4.After receiving the certificate , accept it

certreq -accept c:\certs\cert.cer

 This will install the certificate in your certificate personal folder..
