Hello !		 	 

 One of our  customer have performance problem in following setup.

         A,B,C,D : VAX/VMS DECnet/OSI nodes. (VAX systems)
         X1,X2,X3,X4: X25 routers  (motorola x25 switches)


DECnet/OSI V5.6B & VMS/VAX V5.5-2.

 When he do sethost from node C to node A takes longer duration for connection.
But to all other nodes it works fine. And sethost from other nodes to node A
works fine. Even sethost from node A to node B works fine without any perormance
problem. DECnet is connections are through x.25 DLM circuits.

 telnet from node B to node A works fine. (no performance problem). 
 (our IP setup is like this. UCX is installed on the VAX and Wanrouter is 
  configured as IP router and connected to Motorola switches.


 Can any body tell me what should I look into to solve this problem? 

 Thx in advance
