You receive an "SSO Server failed. The RPC server is unavailable" error message when you try to edit the receive location or the send port in BizTalk Server 2004

In Microsoft BizTalk Server 2004, when you try to edit the receive location or the send port, you may receive an error message that is similar to the following:

This behavior may occur if the following two conditions are true:

• You have previously configured your BizTalk Server to use domain accounts by using the Configuration Framework.
• Your BizTalk Server-based server is not currently connected to the domain.

Under these conditions, the Single Sign-On (SSO) Service may not start.

To work around this behavior, create a hosts file entry that maps the NetBIOS name of the computer to 127.0.0.1. Typically, the hosts file is located in the C:\Windows\System32\Drivers\Etc\Hosts folder. For example, the following entry in the hosts file maps the NetBIOS name "SomeNetBIOSName" to 127.0.0.1:You can use Notepad to open and to edit the hosts file.
