Microsoft offers a service called the Certificate Wizard which is used in conjunction with Microsoft's Internet Information Services. Sometimes, when users try to generate a certificate request using this service, they are unable to find the Server Certificate button.
ProblemAccording to Microsoft, this error occurs because of a problem with a particular file. This file is entitled "Xenroll.dll". If this file is not properly registered, the Server Certificate button will be unavailable.RegistrationTo register this file, open Windows Explorer, enter the WinNT directory and click on System32. Then, enter the Start menu, click on Run and enter Regsvr32. Then, drag Xenroll.dll from the System 32 directory into the Run text box and click OK.Further ResolutionsIf this does not solve the problem, Microsoft suggests that users try registering two more files using the same steps. These are entitled "system32inetsrvcertmap.ocx" and "system32inetsrvcertwiz.ocx". iphone to computer transfer
