Environment
Micro Focus Client for Open Enterprise Server 2 SP4 IR4
Open Enterprise Server 11 SP 2
Open Enterprise Server 11 SP 2
Situation
When trying to log in on the server, an error is displayed:
Internal error -941293548 (0xC7E50014)
Internal error -941293548 (0xC7E50014)
Resolution
The problem lies in the network setup; routing needs to be adjusted:
1. Add a routing rule to the default gateway to send all traffic with a destination address of the server's IP address to the L4 switches IP address.
or
2. Add a routing rule to the Windows PC to send all traffic with a destination address of the server's IP address to the L4 switches IP address.
Cause
The OES server is behind an L4 switch. Clients do not know about the server IP address/name, they contact the L4 switch, and the switch forwards the NCP/NDS traffic to the server.
The initial NCP connection completes successfully, but then the server sends its real IP address as a reply to the client request "NDS Get Server Address", so when the Client tries to open the second NCP connection, it uses the real server IP, which fails because clients do not have direct access to the server.

Additional Information
When trying to open the second NCP connection, an ICMP packet is returned from default gateway, with time-to-live marked as expired, as server lies on a different subnet as the client so not even the default gateway can route the packet properly.
