Plesk 11.x / Windows :: Cannot Rename Domains In Panel

I'm trying to rename a domain in my panel and keep getting the following error:

Code:
Error: Execute websrvmng --rename-vhost "--old-name=domainb.com" "--new-name=domaina.com" failed with error code 1: External component has thrown an exception. In IIS7NativeProvider module Exception type: System.Runtime.InteropServices.SEHException at _CxxThrowException(Void* , _s__ThrowInfo* ) at IIS7ApplicationPools.copy(IIS7ApplicationPools* , auto_ptr<IApplicationPool>* , basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t> >* srcName, basic_string<wchar_t,std::char_traits<wchar_t>,std::allocator<wchar_t> >* dstName)
Running

Code:
websrvmng --rename-vhost "--old-name=domainb.com" "--new-name=domaina.com"

In the Windows command line gives the following error:

Code:
Cannot find domain by name 'domaina.com'

Haven't found many leads on the web as to what this might be.
