RAS Error: TCP/IP CP Reported Error 733: The PPP Control...

• Microsoft Windows NT Server version 4.0
• Microsoft Routing and Remote Access Service Update for Windows NT Server 4.0

SYMPTOMS

When you attempt to connect a Remote Access Service (RAS) client to your multihomed RAS Server or Routing and Remote Access Service (RRAS) Server, which is also a Dynamic Host Configuration Protocol (DHCP) server, the client may get the following error:

   TCP/IP CP reported error 733: The PPP control protocol for this network
   protocol is not available on the server.

   Event ID   : 1011
   Source     : DhcpServer
   Description: The DHCP server issued a NACK to the client
                (5241532090DAE6D09FD4BC0101000000) for the address
                (160.62.1.126) request.

   NOTE: The hardware address and the IP address above will be different
   for your network environment.

   Event ID   : 20091
   Source     : RemoteAccess
   Description: The remote Access Server was unable to acquire an IP
                Addresss from the DHCP Server to be used on the Server
                Adapter. Incoming user will be unable to connect using IP.

RESOLUTION

To work around this issue, you will need to reconfigure your RAS server to use a static pool of IP addresses. If the addresses that you use exist within the scope of addresses in your DHCP server scopes, you also need to exclude the range in DHCP Manager.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
