&nbsp;I'm evaluating FB at the moment and I cannot get the IIS tasks to work.

I'm running on 64bit Windows 7 with IIS 7.5 and when I add an application pool task I cannot connect to IIS to obtain the list of application pools and when I manually enter an app. pool name and try to run the task I get the error:&nbsp;Could not establish connection to IIS server. Invalid namespace&nbsp;

I've tried leaving everything blank and entering host name an credentials, but neither work.

&nbsp;

Any ideas?

&nbsp;

Nick

Hi Nick,   
  
 Can you check and make sure you have the ‘IIS Management Scripts and Tools’ option installed on the machine (Control Panel -\> Programs and Features -\> Turn Windows features on or off).   
  
 Regards,   
 Paul.

They were not installed, but installing them just changed the error at runtime to

> Could not ‘Stop’ the application pool. Provider load failure

&nbsp;OK. I can run the task if I run FB as administrator, but I still can't connect to get the list of Application Pools when editing the task.

I really don't want to run FB as administrator, can you suggest any workaround?

Hi Nick,   
  
 \> I really don’t want to run FB as administrator, can you suggest any workaround?   
  
 Sorry Nick, we can not workaround this as it’s a security feature of Windows.   
  
 \> but I still can’t connect to get the list of Application Pools when editing the task.   
  
 Does this still occur when running as administrator? What is the error message that you receive?
