I Have a WS2003R2 (x64) Enterprise Root CA that gives me a 0x1a8 when using the web enrollment website to request a certificate. "Unexpected Error getting the templates list".
This issue can occur if IIS is running in IIS 5.0 Isolation Mode. Please uncheck the check box and restart IIS. If the issue persists, unregistered and reregistered the files that are responsible for the web enrollment by running the following commands:
regsvr32 /u scrdenrl.dll
regsvr32 scrdenrl.dll
regsvr32 /u xenroll.dll
regsvr32 xenroll.dll
Note: Press Enter after each command.
And then, restart the IIS again to see if the issue goes away.

Your information also help me to resolve the problem with the same error that happened after I install .NET Framework 1.1 on Windows Server 2003 R2 x64 that already had .NET Framework 2 installed.
