This article discusses an issue that can occur during the take control of the source server process.
Applies to:  PowerP2V V4.0.2 and higher



When performing a conversion with the PowerP2V Server installed on a Windows 2003 Service Pack 1 server, the conversion job fails at Step 6.3.1: Taking Control and the following error is displayed:

Unable to take control of server
The request failed with HTTP status 401: Unauthorized.
Started: 02/05/2005 1:07:08 PM
Completed: 02/05/2005 1:10:36 PM




As per Microsoft KB896861, this is most likely to occur if the Default Web site in IIS where the PowerP2V Server is installed uses Integrated Authentication and has a name that is mapped to the local loopback address.

To resolve the issue, please refer to the recommended methods outlined in KB896861:;en-us;896861
